poppr 2.9.6

MISC

  • Poppr itself will no longer accidentally modify the random seed when it is attached (found by @timtaylor, #259)

poppr 2.9.5

CRAN MAINTENANCE

  • The usenames option from xcolor has been removed from the algorithms and equations vignette.
  • Old documentation has been fixed to conform with CRAN standards.

poppr 2.9.4

CRAN MAINTENANCE

  • a function declaration was added for SEXP omp_test()
  • failing tests were fixed.
  • code where object classes were compared with == was fixed to use inherits()

DEPENDENCIES

  • {RClone} has been removed as a suggested package as it was archived on CRAN some time ago.

poppr 2.9.3

CRAN MAINTENANCE

  • C headers were re-arranged to place R-specific headers after OMP headers to avoid problems in clang 13 (@zkamvar, #246).

poppr 2.9.2

CRAN MAINTENANCE

  • A test for bruvo.between() was fixed in a superficial way to avoid an error on CRAN R-devel (@zkamvar, #242).

poppr 2.9.1

DEPENDENCY UPDATE

  • The {phangorn} package is no longer imported. We only used one line of code from the package (upgma), so we copied over the implementation with the author's permission (@KlausVigo, #237).

poppr 2.9.0

NEW FEATURES

  • bruvo.between() will calculate bruvo's distances between a query dataset and a reference dataset (@davefol, #223)

DEPRECATION

  • The argument blacklist has been deprecated in favor of exclude for the following functions: bruvo.msn(), poppr.msn(), clonecorrect(), poppr(), mlg.table(), mlg.crosspop(), and popsub(). It will be removed in the poppr version 2.10 (@zkamvar, #218)

GITHUB

  • The default branch for the repository is now "main" (@zkamvar, #218)

BUG FIX

  • genind2genalex() no longer converts diploid sequence data to zeros on export This fixes #231 (@zkamvar, #233).
  • bitwise.ia() will no longer have integer overflows early on Windows (@zkamvar, #235)

poppr 2.8.7

CRAN MAINTENANCE

  • Links to other packages are now formatted correctly.

poppr 2.8.6

BUG FIX

  • read.genalex() now can import columns with entirely "T" alleles as "T" instead of "TRUE". (See #214 for details).

NEW IMPORTS

  • Progress bars are now implemented via the {progressr} package, which gives the user control over what should be displayed (or not). For example, to get auditory updates instead of a progress bar, you can use the "beepr" package and set progressr::handlers("beepr"). This will play an alert for each step (~50) and a final sound. To suppress all progress bars entirely, you can use progressr::handlers("void"). These progress bars have replaced the utils::txtProgressBar() and dplyr::progress_estimated() bars.

poppr 2.8.5

CRAN MAINTENANCE

  • The output from the poppr() function will no longer contain factor columns for the population names or the file names. This is due to R 4.0.0 changing behavior with the stringsAsFactors default in data.frame(). (See https://github.com/grunwaldlab/poppr/issue/212 for details).

poppr 2.8.4

CRAN MAINTENANCE

  • Update documentation for S4 method

poppr 2.8.3

BUG FIX

  • read.genalex() now correctly parses strata when the user imports data that contains duplicated data AND has some individuals named as integers less than the number of samples in the data (prepended by zeroes) (See #202).

NEW FEATURES

  • MSN functions: nodes with single populations displayed as circles instead of pies. (@fdchevalier, #203)

MISC

  • mlg.vector() is now safer as it now uses a for loop instead of a function with the out-of-scope operator (<<-) (see #205)
  • shufflepop() is now safer as it now uses a for loop instead of a function with the out-of-scope operator (<<-) (see #205)
  • The MLG class gains a new distenv slot, which will store the environment where the distance function or matrix exists. This is accompanied by an accessor of the same name (see #206).
  • "mlg.filter<-"() replacement methods will no longer search the global environment when evaluating the distance function or matrix (see #206).
  • Tests for mlg.filter() no longer assign objects to the global environment
  • DOIs for the publications have been added to the DESCRIPTION

poppr 2.8.2

MISC

  • Tests relying on randomization were updated before R 3.6.0, which fixes a biased randomization. This has no visible impact on users. See #198 for details.

poppr 2.8.1

BUG FIX

  • An error that appeared in some AMOVA calls with genind objects with character- based alleles was fixed (see #190 for details)

DOCUMENTATION

  • aboot() documentation was updated to add the citation and make clear its purpose and limitations.

MISC

  • DOIs have been hyperlinked to doi.org instead of dx.doi.org (#188, @katrinleinweber)

poppr 2.8.0

BUG FIX

  • win.ia() now has more consistent behavior with chromosome structure and will no longer result in an integer overflow. (see #179). Thanks to @MarisaMiller for the detailed bug report.
  • plot_filter_stats() will plot stats if supplied a list of thresholds.

ALGORITHMIC CHANGE

  • win.ia() may result in slightly different results because of two changes:
    1. The windows will now always start at position one on any given chromosome. This will result in some windows at the beginning of chromosomes having a value of NA if the first variant starts beyond the first window.
    2. Windows are now calculated for each chromosome independently. The previous version first concatenated chromosomes with at least a window-sized gap between the chromosomes, but failed to ensure that the window always started at the beginning of the chromosome. This version fixes that issue. (see #179).

DEPRECATION

  • The chromosome_buffer argument for win.ia() has been permanently set to TRUE and deprecated as it is no longer used.

NEW FEATURES

  • poppr.amova() will now handle genlight/snpclone objects. See #185 for details.

  • bitwise.dist() now has two new options: euclidean and scale_missing. When both of these are set to TRUE, the distance measured will be Euclidean scaled for the amount of missing data in each comparison. This matches the output of base R's dist() function at a fraction of time and memory. See #176 for details.

  • make_haplotypes() is now a generic defined for both genind and genlight.

  • genind2genalex() will no longer write to "genalex.csv" by default. Instead, it will warn the user and write to a temporary file. See #175 for details.

  • genind2genalex() now has an overwrite parameter set to FALSE to prevent accidental overwriting of files.

  • win.ia() has a new argument name_window, which will give each element in the result the designation of the terminal position of that window. Thanks to @MarisaMiller for the suggestion!

  • pair.ia() can now calculate p-values via permutations. (See #180 for details)

DOCUMENTATION

  • cutoff_predictor() was added to the MLG vignette

MISC

  • The RClone package has been added to suggests (see #187)

poppr 2.7.1

MISC

  • Missing documentation for poppr.amova() has been added.
  • Polysat is now listed in imports.

poppr 2.7.0

NEW FUNCTIONS

  • make_haplotypes() will split your data into pseudo-haplotypes for use in AMOVA-like analyses. This was a previously internal function, but has been promoted to a user-facing function in this version.

  • as.genambig() will convert genind/genclone objects to Polysat's "genambig" class. Note that polysat must be installed for this to work.

ALGORITHMIC CHANGE

  • AMOVA will now default to using euclidean distance. This affects all calculations made with within = FALSE or filter = TRUE without a user-supplied distance. This will not have affect those with haploid or diploid data using within = TRUE. The dissimilarity distance is equivalent to a squared euclidean distance for haploid genotypes, but not for any higher ploidy. Those using filter = TRUE without specifying a distance should use a euclidean threshold. This should not be an issue for those who simply want to group isolates with missing data, however as a zero distance is the same for euclidean and dissimilarity. Thanks goes to Patrick Meirmans for alerting me to this error.

NEW FEATURES

  • AMOVA will now calculate within-individual variance for polyploid data.

MISC

  • printing of AMOVA will now better handle any changes in methods from pegas or ade4.

poppr 2.6.1

BUG FIX

  • An out-of-bounds memory access error in bitwise.dist() was fixed. See #169 for details.

poppr 2.6.0

NEW FUNCTIONS

  • The new function boot.ia() is conceptually similar to resample.ia(), except it resamples with replacement.

NEW FEATURES

  • The function resample.ia() now can resample individuals weighted by their Psex value.
  • The minimum spanning networks will now scale nodes by area instead of radius. This gives a more accurate picture of the differences between MLGs. See #154 for details.
  • A legend for samples/node is now added to all minimum spanning networks. See #158 for details.
  • The imsn() option for node size scale has been changed to a slider.

BUG FIX

  • An issue where data with sample names containing apostrophes could not be imported was fixed (Identified in #156).
  • a bug in imsn() where custom MLGs would result in an error was fixed. See #155 for details.
  • a bug in plot_poppr_msn() where setting scale.leg = FALSE would result in a very small MSN plot was fixed.
  • mlg() now works properly for snpclone and genlight objects. See #155 for details.

DEPENDENCIES

  • The minimum version of igraph has been set to 1.0.0.

MISC

  • The MSN is now plotted last in plot_poppr_msn() so additional legends can be added if necessary.

poppr 2.5.0

ALGORITHMIC CHANGE

  • Identified in #139, Bruvo's distance will now consider all possible combinations of ordered alleles in the calculation under the genome addition and loss models for missing data. This will affect those who have polyploid data that contain more than one missing allele at any genotype

    To facilitate comparison, the global option old.bruvo.model, has been created. By default it is set to FALSE, indicating that poppr should use the ordered allele combinations. If the user wants to use the method considering unorderd allele combinations, they can set options(old.bruvo.model = TRUE)

    It must be repeated that this does not affect haploid or diploid comparisons, those that use the infinite alleles model, or those who do not have more than one missing allele at any genotype.

DEPRECATION

  • The warning for a short repeat length vector for Bruvo's distance is deprecated and will become an error in the future
  • jack.ia is deprecated in favor of resample.ia for clarity.

BUG FIX

  • A bug in read.genalex() where removed samples would have incorrect strata labels was fixed. Thanks to Hernán Dario Capador-Barreto for identifying it. See #147.

MISC

  • The internal plotting function for mlg.table now uses tidy evaluation for dplyr versions > 0.5.0
  • The package reshape2 was removed from imports and replaced with base functions (see #144 for details)

NEW IMPORTS

  • Due to the migration to dplyr version 0.7.0, poppr now imports the "!!" operator from the rlang package

poppr 2.4.1

BUG FIX

  • A corner case where repeat length vectors out of order would be erroneously subset with test_replen() and fix_replen() has been fixed. See #136 for details.
  • All functions that perform filtering will now run serially due to a bug on Fedora machines with at least two threads. Details can be found at #138.

poppr 2.4.0

NEW FUNCTIONS

  • jack.ia() will randomly jackknife your sample to a specified n (default is the number of MLG), and calculate the index of association over multiple iterations, giving a distribution of possible values at a given sample size.

NEW FEATURES

  • The function mlg.table() gains new parameters, "color" and "background". The "color" parameter will create a single barplot with colors representing populations while the "background" parameter will create a background plot showing the abundance of MLGs across populations within the facets.
  • The function win.ia() will now take into consideration chromosomal coordinates when constructing windows. It has additionally acquired a new parameter chromosome_buffer, which allows the user to specify whether or not the window should be limited to within chromosomes.

NOTABLE CHANGES

  • calculation of MLGs for snpclone and genlight objects will be performed via distance-based methods by default. This is in contrast to the previous behavior where individuals were assumed to have unique genotypes. see #125 for details.
  • An error will be thrown when attempting to use mlg.crosspop() with an object that has < 2 populations.
  • genotype_curve() will now remove monomorphic loci before calculation by default as these loci misleadingly influence the shape of the curve. This will change the shape of the curve if you have monomorphic loci. This change IS optional via the drop and dropna parameters, but it is not recommended to change these parameters.
  • The calculation for psex() has changed to be more accurate when using method = "multiple". It also gains the ability to use several values of G, one for each population. Documentation for psex() has also been improved. For details of the change, see #101

BUG FIX

  • The error given when a genlight object is passed to poppr() now correctly identifies the substitute function as diversity_stats() and not diversity table (see #123).
  • GenAlEx files imported with duplicate loci will generate a warning telling the user that the duplicated loci have been renamed (usually to _1) (see #122).
  • Haplodiploids imported in genalex files will be properly treated (see #124).
  • read.genalex() will now implicitly check for the correct number of individuals in the data (see #128).
  • The function poppr() no longer throws an error if the sample > 0 and the data has no population (see #130).
  • A bug where round-robin allele frequencies calculated with by_pop = TRUE were inaccurate for all but the first population was fixed. For details, see #132.
  • A potential integer overflow was fixed in SEXP association_index_haploid. This was a ghost from #100.
  • PROTECT statements were placed around allocation statements. For details, see #133.

MISC

  • The documentation for bitwise.dist() clarifies the role of the differences_only flag (see #119).
  • Interruptions in C code is now handled gracefully via R_CheckUserInterrupt(). The benefit is that long-running calculations are interrupted near instantly, but at the cost of a few more milliseconds of computation time. (see #86)
  • Bruvo's distance now has complete tests for recursion as of commit 4e4fa40d16

poppr 2.3.0

NEW FUNCTIONS

  • The function bootgen2genind() will help users take advantage of bootstrapping distance functions from other packages that require genind objects. For details, see #112 and #111

NEW FEATURES

  • There is now a plot parameter for the genotype curve to enable or suppress plotting.
  • Progress bars are now automatically suppressed when running non-interactively. to turn them on when running non-interactively, use options(poppr.debug = TRUE).
  • The progress bar for ia() and poppr() will now show estimated time. This is from dplyr's progress_estimated().

MISC

  • The hist argument in the ia() is deprecated in favor of plot.
  • The x axis for the genotype_curve() plot is now numeric, allowing you to fit a smoothing function over the points without having to use the hack geom_smooth(aes(group = 1)). This is thanks to Kara Woo for pointing this out on twitter (https://twitter.com/kara_woo/status/783336540407685120).
  • The "show" method for genclone objects now delimits populations and strata by a comma, avoiding confusion with multi-word population names. Thanks to @knausb for the fix in #116.
  • Documentation for poppr.amova now contains a note about significance testing with the ade4 function randtest.amova.

BUG FIX

  • The subsetting methods will now properly handle mlgs when using sample names to subset genclone and snpclone objects. See #114 for details.
  • A plotting bug for mlg.table() was fixed so that the plots now show the maximum value.
  • Bugs with subsetting bootgen and bruvomat objects with no loci specified were fixed. See #118 for details.

poppr 2.2.1

BUG FIX

  • A problem exporting haploid sequence data to genalex format was fixed (see #108)
  • Data without population structure no longer throws an error in imsn()

NEW FEATURES

  • You can now specify layout parameters in imsn()

BUG FIX

  • An issue that caused errors in the imsn() code output was fixed (see #93)
  • Caught bug where the mlg.filter() assignment method was using nei.dist() instead of diss.dist() when no distance was specified.
  • A bug that resulted in significantly negative values from bitwise.ia() with large sample sizes was fixed. Spotted by @knausb (see #100)
  • Fixed issue where plot_filter_stats() wasn't displaying the full range of MLGs
  • Color vectors are now correctly parsed when passed to msn functions (see #55) for details. Long color vectors are now accepted, albiet with warning.
  • An issue where mll.reset() did not reset non-MLG class objects in the mlg slot was fixed.

MISC

  • Documentation for mlg.filter() was clarified and updated with more examples.
  • The vignette "Migration from poppr version 1" has been removed.

  • read.genalex() will no longer fail if missing data is not coded as zero; see #84 for details
  • missingno() no longer removes genotypes AT specified threshold; see #90 for details

poppr 2.1.0

IMPROVEMENTS

  • The internal code for the genotype_curve has been implemented in C for a 10x increase in speed.

NEW FEATURES

  • poppr.msn, bruvo.msn, and plot_poppr_msn gain the ability to take character vectors for color palettes. See issue #55 (#55) for details.
  • plot_poppr_msn returns the modified graph.
  • All functions related to Bruvo's distance can now take a named vector of repeat lengths in any order. See issue #61 (#61) for details.
  • aboot gains the argument strata so that you can automatically convert genind to genpop.
  • genotype_curve can now take in loci objects from pegas.
  • You can now specify the maximum number of loci to analyze in genotype_curve.

  • psex will calculate the probability that an observed genotype will be observed more than once by chance.

NEW TRADITIONALISTS

  • because we're through being cool.

MISC

  • Documentation for genclone and snpclone classes are more coherent.
  • Accessors added for internal MLG objects (for developers).
  • The genotype accumulation curve displays the iteration and locus number instead of a progress bar.
  • The genotype accumulation plot is now scaled from 0 to the number of observed mlgs.
  • Documentation for poppr.amova no longer references the "hierarchy" slot.

BUG FIX

  • Single locus data sets can now be read in with read.genalex. This was brought up in issue #58 (Thanks to Nick Wong for spotting it).
  • A bug in informloci where the MAF argument wasn't being applied to P/A data has been fixed.
  • Printing of genclone objects with mixed ploidies previously reported erroneously due to a sorting error. This has been fixed.
  • Edge case where a missing cell in the genalex matrix was interpreted as a literal "NA" was fixed.
  • msn functions now return nodes that are correctly named. See Issue #66 (#66) for details.

poppr 2.0.2

  • read.genealex can now correctly import missing data for diploids (issue #42)

NEW FEATURES

  • Startup message now tells you if poppr was compiled with OMP support.

poppr 2.0.0

COMPATIBILITY UPDATE

  • poppr has moved to version 2.0 due to adegenet's recent update. The hierarchy slot introduced in version 1.1 is now being moved to adegenet and renamed strata. For maximum backwards compatibility, all of the hierarchy methods still exist, but they are deprecated and will print a warning with the proper function to use. If you were accessing the hierarchy slot without using the *hierarchy() methods, your code will fail as the hierarchy slot now should only contain a formula object.

NEW DEPENDENCIES

  • poppr now imports elements from dplyr and shiny
  • As required as of 2015-06-29, poppr now explicitly imports: stats, graphics, grDevices, and utils

NEW DATA

  • A data set called Pram containing SSR genotypes from the Sudden Oak Death pathogen Phytophthora ramorum (Kamvar et.al., 2015)

NEW MINT FLAVOR

  • refreshing!

NEW FEATURES

  • The default plot for the index of association will now be a single histogram. The user has the option to visualize the standardized index of association (index = "rbarD", default) or the classic index of association (index = "Ia"). If the user uses the function ia with the argument valuereturn = TRUE, then the resulting object can be plotted with the plot function.
  • The function poppr will now plot all populations in a single faceted plot instead of one plot per population.
  • aboot and bruvo.boot will now be able to utilize any function to generate trees (suggested in issue #18).
  • The mlg slot in the genclone object can now optionally hold an MLG class object. This object will contain different definitions of multilocus genotypes, allowing the user to switch between observed, custom, and mlgs defined given a genetic distance threshold.
  • minimum spanning network functions gain the ability to include reticulations using the option include.ties
  • minimum spanning network functions gain the ability to collapse multilocus genotypes by genetic distance with the option threshold.
  • poppr.amova gains the ability to filter multilocus genotypes before calculation.
  • informloci gains the argument "MAF", which allows the specification of a minor allele frequency cutoff in addition to the cutoff argument. Examples have been updated.
  • aboot can now take genlight objects.
  • poppr.msn and plot_poppr_msn can now take genlight objects.
  • plot_poppr_msn now gives users the option to exclude the legends.
  • Default plotting for mlg.table will no longer produce one plot per population. It will now produce a single ggplot object for all populations. Note that the bars are no longer colored by count.
  • poppr will no longer calculate "Hexp". Instead, Simpson's index will be calumniated, but the old index can be retrieved by using (N/(N - 1))*lambda.
  • poppr can now take any statistic that can be calculated from a table of multilocus genotype counts.
  • genind2genalex gains the ability to selectively write different strata.

NEW FUNCTIONS

  • mlg.filter will contract multilocus genotypes given a genetic distance and threshold using one of three algorithms. It can report statistics such as the multilocus genotypes returned, the number of samples within each multilocus genotype, the thresholds at which multilocus genotypes were collapsed, and the genetic distance matrix that represents the new multilocus genotypes.
  • filter_stats will show you graphical output of all the algorithms in mlg.filter.
  • cutoff_predictor will predict the cutoff threshold from mlg.filter.
  • bitwise.dist can efficiently calculate absolute genetic distance for genlight objects.
  • mll "multilocus lineages" is a new replacement for mlg.vector which gains the functionality of selecting the multilocus genotype definition from the mlg slot.
  • nmll counts the number of multilocus lineages
  • mll.custom allows the user to define custom multilocus genotypes.
  • mll.levels allows the user to edit the names of custom multilocus genotypes.
  • poppr_has_parallel will return TRUE if poppr was built with OpenMP parallel library.
  • win.ia calculates windows of \bar{r}_d along genlight chromosomes.
  • samp.ia calculates \bar{r}_d for genlight object by randomly sampling a user-defined number of SNPs.
  • test_replen will test repeat lengths of microsatellite markers for consistency.
  • fix_replen will fix inconsistent repeat lengths for microsatellite markers.
  • diversity_stats returns a matrix containing diversity statistics. Defaults to 4 found in poppr, but can be extended to any statistic that can be calculated on a vector of MLG counts.
  • diversity_boot will bootstrap a MLG matrix over the statistics specified for get_stats. Can also perform rarefaction bootstrap.
  • diversity_ci will calculate and plot confidence intervals for bootstrap resampling of an MLG matrix. This includes rarefaction to the smallest sample size.
  • imsn provides an interactive shiny interface for construction of minimum spanning networks.
  • pair.ia will calculate the index of association for pairs of loci and plot heatmaps.

NEW CLASSES

  • snpclone is an extension of the genlight object that acts very much like genclone. It contains an mlg slot.
  • MLG is an internal class that lives inside the mlg slot of snpclone and genclone objects. It allows the user to easily switch between multilocus genotype definitions.

BUG FIXES

  • I was going too fast to count.

NAMESPACE CHANGES

  • poppr no longer depends on pegas.
  • ade4 and reshape2 are now explicitly required.

IMPROVEMENTS

  • default shuffling algorithm has been implemented in C to increase speed.
  • output of the mlg functions are now represented as integers to decrease their size in memory.
  • mlg.matrix is now calculated faster utilizing R's internal tabulating capabilities.
  • The function poppr will no longer return rounded results, but rather is printed with three significant digits.

MISC

BUG FIX UPDATE

  • Made last bug fix more stable (corrected on ape side).

poppr 1.0.6

BUG FIX

  • Fixed bug for users who have downloaded ape version 3.1 or higher where bruvo.boot would throw an error.

MISC

  • Updated citation information.

poppr 1.0.5

NOTABLE CHANGE

  • The default shuffling algorithm for calculating the index of association has changed from multilocus-style sampling to permutation of alleles. All of the 4 methods are available, but new assignments are as follows: Method 1: permute alleles, Method 2: parametric bootstrap, Method 3: non-parametric bootstrap, Method 4: Multilocus-style sampling. Previously, Multilocus was 1 and the rest followed in the same order. There should be no compatibility issues with this change. Functions affected: ia, poppr shufflepop

BUG FIX

  • Bootstrapping algorithm for bruvo.boot function was not shuffling the repeat lengths for each locus resulting in potentially erroneous bootstrap support values. This has been fixed by implementing an internal S4 class that will allow direct bootstrapping of the data and repeat lengths together.
  • An occasional error, "INTEGER() can only be applied to a 'integer', not a 'NULL'" in bruvo.boot or bruvo.dist fixed.

IMPROVEMENTS

  • Changes to bruvo.boot allow for ever so slightly faster bootstrapping.

MISC

  • Permutations for I_A and \bar{r}_d are now visualized as a progress bar as opposed to dots.

poppr 1.0.4

BUG FIX

  • A previous error where bootstrap values greater than 100 were reported from bruvo.boot on UPGMA trees has been fixed.
  • Fixed correction of negative branch lengths using Kuhner and Felsenstein (1994) normalization for NJ trees.

MISC

  • github repository for poppr has changed from github.com/poppr/poppr to github.com/grunwaldlab/poppr

poppr 1.0.3

IMPROVEMENTS

  • Optimized internal sampling function to run up to 2x faster.
