The inaugural version of {gggda} was spun off the post-v0.1.1 development version of {ordr}. Upgrades to {ordr} components since that release that are included in {gggda} are listed here.
Unit tests have been written for all ggproto shortcuts.
Two new coordinate systems provide control over the aspect ratio of
the plotting window without compromising that of the (artificial)
coordinate axes: GeomRect (alias GeomSquare)
extends GeomFixed with an window_ratio
parameter for the plotting window, while GeomBiplot removes
the ratio parameter and forces the coordinate axes to have
aspect ratio 1.
The ‘vector’ and ‘text_radiate’ geoms have been combined. The
shortcut geom_text_radiate() is deprecated, and
geom_vector() generates radiating labels by default.
The ‘axis’ and ‘isoline’ geoms hit trouble when one or more points
lay at the origin (x^2 + y^2 == 0). These cases have now
been removed in setup_data().
The ‘center’ and ‘star’ stats now follow the ‘summary’ stat
convention of using fun, so fun.center is
deprecated. Additionally, fun.ord accepts a function that
summarizes the columns of a matrix, which accommodates summaries like
the depth median that do not decompose along orthogonal axes.
Previously, underscore-separated parameters like
label_colour were used to specify secondary aesthetics,
i.e. aesthetics for graphical objects other than those considered
“primary” for the layer. Their behavior has been debugged by mimicking
the use of period-separated parameters like label.colour in
{ggplot2} v3.5.1, except for the new bagplot geom, for which their
behavior is based on that of geom_boxplot() in the current
development version of {ggplot2}. This induces some breaking changes due
to the renaming of most, and the removal of some, such parameters.
The simple and experimental StatScale has been
deprecated.
A new statistical transformation serves to parent specific
“referential stats”, meaning those that depend on non-inherited (in this
setting, positional) data to transform the inherited data. The reference
data are passed to the new referent parameter. The new stat
is coupled with an additional LayerRef class that enables
ggplot_add() to pass the inherited positional aesthetics to
$setup_params(). Biplot-specific stat_*_*()
shortcuts accept additional argument types to referent that
result in the opposite matrix factor being used as reference data.
A new ‘rule’ statistical transformation computes additional position
aesthetics that the ‘axis’ geom uses to limit and offset axes. The stat
is referential and expects a set of functions that compute limits
lower and upper along the axes and
yintercept and xintercept associated with
offset axes. The ‘axis’ geom preprocesses these aesthetics to rule
endpoints xmin,ymin,xmax,ymax and offset vectors
xend,yend to force the plotting window to contain the
limited axis segments or, if the axes remain lines, the offsets where
they are centered.
A new ‘peel’ statistical transformation computes nested convex hulls containing specified fractions of data.
A new ‘depth’ statistical transformation estimates depth across a
grid and is paired with GeomContour to produce depth
contours, which can be used to plot alpha bags.
Aided by element standardization, the classic density_2d
statistical transformation and geometric construction are adapted to
biplots. Currently, source code generation does not respect fixed
parameters passed to layer() by the stat_*()
and geom_*() shortcuts; as a consequence,
contour = TRUE must be manually passed to
geom_*_density_2d().
linewidth
aesthetic (breaking change)An upcoming release of {ggplot2} controls stroke width using the new
linewidth aesthetic rather than size. This
{ordr} release adapts to this change internally for
GeomUnitCircle and by updating row and column layers
automatically adapted from {ggplot2}. (#50)
Methods are added for the ‘eigen’ class returned by
eigen(), and the internal eigen_ord() function
and its methods are updated accordingly.
The previous version extended the ‘list’ method for {broom}’s
tidy() and glance() functions to recognize the
output of cmdscale() and of cancor(). These
have been spun off to a nascent helper package, {broom.list}, to reduce
size and prevent attachment warnings.
In addition to minor changes, the following substantive changes are made from v0.0.2:
The column names of augment_ord() and
tidy() outputs are no longer prefixed by periods.
A new list tidier for cancor() output is introduced.
Tools to negate a subset of artificial dimensions, adapted from the sandboxed set of alignment tools, are provided.
The ordinate() function is now a generic with methods
for four data classes.
The logical prediction parameter is replaced with the
character-valued axis.type, based on the
ax.type parameter used in {UBbipl} (Gower, Gardner–Lubbe,
& le Roux, 2011).
Unit tests are overhauled to remove contexts, omit ad hoc tests, standardize method tests, and cover additional methods.
The term ‘accessor’, used to refer to S3 class methods to recover standardized model components, has been changed to ‘recoverer’.
This pre-release makes several substantive changes in preparation for CRAN submission.
Annotation of active and supplementary elements is standardized: The
character augmentation .element replaces the logical
.supplement, and class methods either omit it entirely
(when all retrieved elements are active) or include it in both row and
column augmentation (when either includes supplementary elements). The
value of .element is either ‘active’ or a type of
supplement, e.g. ‘score’.
Extraneous dependencies are dropped to reduce overhead. This takes two forms:
The Description field in DESCRIPTION is expanded and
documentation throughout is slightly revised, including some new
references.
This is a pre-release in anticipation of a first CRAN submission. Upgrades between this pre-release and CRAN submission will focus on addressing issues.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
