gggda 0.1.0

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.

infrastructure and standards

unit tests

Unit tests have been written for all ggproto shortcuts.

new coordinate systems

GDA-geared coordinate systems

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.

up( or down)grades to existing plot layers

combined vector and radiating text geom (breaking change)

The ‘vector’ and ‘text_radiate’ geoms have been combined. The shortcut geom_text_radiate() is deprecated, and geom_vector() generates radiating labels by default.

debugged axis geom

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().

reconciliation of summary functions

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.

revamped handling of secondary aesthetics (breaking change)

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.

deprecation of scale stat

The simple and experimental StatScale has been deprecated.

new plot layers

referential stats

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.

rule stat

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.

peel stat

A new ‘peel’ statistical transformation computes nested convex hulls containing specified fractions of data.

depth stat

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.

adapted density stat & geom

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().

ordr 0.1.1

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)

class ‘eigen’

Methods are added for the ‘eigen’ class returned by eigen(), and the internal eigen_ord() function and its methods are updated accordingly.

list tidiers (breaking change)

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.

ordr 0.1.0

In addition to minor changes, the following substantive changes are made from v0.0.2:

augmentation

The column names of augment_ord() and tidy() outputs are no longer prefixed by periods.

list tidiers

A new list tidier for cancor() output is introduced.

negation

Tools to negate a subset of artificial dimensions, adapted from the sandboxed set of alignment tools, are provided.

convenience function

The ordinate() function is now a generic with methods for four data classes.

ggbiplot

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).

tests

Unit tests are overhauled to remove contexts, omit ad hoc tests, standardize method tests, and cover additional methods.

documentation

The term ‘accessor’, used to refer to S3 class methods to recover standardized model components, has been changed to ‘recoverer’.

ordr 0.0.2

This pre-release makes several substantive changes in preparation for CRAN submission.

element types

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’.

dependencies

Extraneous dependencies are dropped to reduce overhead. This takes two forms:

  1. Methods for classes from specialty (lower-priority) packages ({candisc} and {ca}) are moved to {ordr.extra} and replaced with methods for classes from higher-priority packages ({stats} and {MASS}).
  2. One-off uses of specialty packages for examples and vignettes are replaced.

documentation

The Description field in DESCRIPTION is expanded and documentation throughout is slightly revised, including some new references.

ordr 0.0.1

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.
