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 to longest_flat_spot() to
    more accurately describe the feature.
  • gg_season() and ggsubseries() 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 use stats::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 with stats::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 use components().
    For example, tourism %>% STL(Trips) is now tourism %>% model(STL(Trips)) %>% components().
    This change allows for more flexible decomposition specifications, and better interfaces for decomposition modelling.

Bug fixes

  • Fixed bug with feat_spectral() not showing results.
  • Fix warning in ACF(), PACF() and CCF() for tidyr change.
  • gg_tsdisplay() will no longer fail on non-seasonal data with missing values. The last plot will instead show a PACF in this case (#76)
  • Better handling of perfect fits in stat_arch_lm() (#85)
