tapered argument to ACF() and
PACF() for producing banded and tapered estimates of
autocovariance (#1).gg_season() now allows seasonal period identifying
labels to be nudged and repelled with the labels_repel,
labels_left_nudge, and labels_right_nudge
arguments.gg_season() behaviour of max_col has been
restored, where colours aren’t used if the number of subseries to be
coloured exceeds this value. The default has changed to Inf
since this function now supports continuous colour guides. A new
argument max_col_discrete has been added to control the
threshold for showing discrete and continuous colour guides (#150).guerrero() method to maintain a consistent
subseries length by removing the first few observations of needed. This
more closely matches the described method, and the implementation in the
forecast package.grid.draw() method for ensemble graphics
(gg_tsdisplay() and gg_tsresiduals()). This
allows use of ggsave() with these plots (#149).generate(<STL>) returning
$.sim as a num [1:n(1d)] instead of
num [1:72] (fable/#336).gg_season() incorrectly grouping some
seasonal subseries.CCF() now matches stats::ccf()
x and y arguments (#144).Minor release for compatibility with an upcoming ggplot2 release. This release contains a few bug fixes and improvements to existing functionality.
gg_tsresiduals() function now allows the type of
plotted residual to be controlled via the type
argument.STL()
decompositions. For data with a single seasonal pattern, the window has
changed from 13 to 11. This change is based on results from simulation
experiments.seasonal::seas() defaults were not
being used in X_13ARIMA_SEATS() when
defaults = "seasonal" (#130).gg_subseries() on data with spaces in
the index column name (#136).... in ACF(),
PACF(), and CCF() with y (and
x for CCF()) arguments. This change should not
affect the code for most users, but is important for the eventual
passing of ... to acf(), pacf()
and ccf() in a future version (#124).Small patch to fix check issues on Solaris, and to resolve
components() for automatically selected transformations in
X_13ARIMA_SEATS().
X_13ARIMA_SEATS() decomposition method. This is a
complete wrapper of the X-13ARIMA-SEATS developed by the U.S. Census
Bureau, implemented via the seasonal::seas() function. The
defaults match what is used in the seasonal pacakge, however these
defaults can be removed (giving an empty default model) by setting
defaults="none".X_13ARIMA_SEATS() method officially deprecates
(supersedes) the X11() and SEATS() models
which were previously not exported (#66).generate() method for STL()
decompositions. The method uses a block bootstrap method to sample from
the residuals.fitted() and residuals() methods for
STL() decompositions.guerrero() default lower bound for Box-Cox
lambda selection to from -1 to -0.9. A transformation parameter of -1
typically results from data which should not be transformed with a
Box-Cox transformation, and can result in very inaccurate forecasts if
such a strong and inappropriate transformation is used.A minor release to fix check issues introduced by changes in an upstream dependency.
gg_season() labels are low aligned outward (#115).gg_season() and gg_subseries() (#117).gg_season()gg_lag() facets are now displayed with a 1:1 aspect
