CRAN v0.1.5
Improvements
gg_lag()
facets are now displayed with a 1:1 aspect ratio.- Season and subseries plots of numeric index data now starts at the earliest
measured observation, rather than assuming a meaningful 0 (#111). - The
n_flat_spots()
function has been renamed tolongest_flat_spot()
to
more accurately describe the feature. gg_season()
andggsubseries()
date structure improvements.- Documentation improvements
Breaking changes
- The
n_flat_spots()
return name is now "longest_flat_spot" to better describe
the feature.
CRAN v0.1.4
Minor patch to resolve upstream check issues introduced by dplyr v1.0.0 and
tsibble v0.9.0.
New features
- Circular time plots are now supported by setting
polar = TRUE
in
gg_season()
.
Improvements
- Added partial matching of the type argument in
ACF()
. - Updated
feat_spectral()
to usestats::spec.ar()
instead of
ForeCA::spectral_entropy()
. Note that the feature value will be slightly
different due to use of a different spectral estimator, and the fix of a
bug in ForeCA.
Bug fixes
- Fixed the minimum data length for seasonal estimation in
feat_stl()
.
CRAN v0.1.3
Improvements
- The axis for
gg_lag()
have been reversed for consistency withstats::lag.plot()
. - Graphical improvements for displaying weekly seasonality in season and subseries plots.
- Added intermittency features available in
feat_intermittent()
Bug fixes
- Fixed the sprectral density plot in
gg_tsdisplay()
not working with plotting expressions of data. - Fixed issue with
gg_subseries()
erroring when certain column names are used (#95). - Fixed issue with environment handling in
STL()
specials.
CRAN v0.1.2
Improvements
var_tiled_var()
no longer includes partial tile windows in the computation.- Added residual acf features to
feat_stl()
. - Performance improvements.
Breaking changes
- Decompositions are now treated as models.
To access the decomposed values, you will now have to usecomponents()
.
For example,tourism %>% STL(Trips)
is nowtourism %>% model(STL(Trips)) %>% components()
.
This change allows for more flexible decomposition specifications, and better interfaces for decomposition modelling.
Bug fixes
