First CRAN submission. This release settles the public API before the package has any users to break, so it carries deliberate breaking changes.
plot_regr() is renamed plot_regression(). Every other interactive/plot
pair already matched its gadget name; this was the last one that did not.
There is no deprecation shim — the package has never been released.
interactive_matrix_inverse() drops the _init suffix from its arguments:
x1_init, y1_init, x2_init, y2_init are now x1, y1, x2, y2.
They now match plot_matrix_inverse(), so do.call() works between them.
All eight interactive_*() gadgets return a new reproduction object when you
click Done. Previously interactive_matrix_inverse() and
interactive_t_test() returned nothing at all, and
interactive_moderation_3d() returned the data frame while discarding the
viewing angles the gadget exists to set. interactive_pca() no longer
returns a two-element list(points, pca); the points come back directly and
the prcomp result is attached as an attribute.
Every gadget prints the plot_*() call that reproduces what was on screen
when you click Done, with arguments still at their defaults omitted. The
returned object is a plain list (settings-style gadgets) or a plain data
frame (points-style gadgets), so do.call(plot_fn, result), nrow(), [
and passing the result straight back to the plot function all work. See
?"compstatslib-reproduce".
Derived state that a user would not retype rides along as an attribute
rather than cluttering the printed call: attr(result, "pca") from
interactive_pca(), attr(result, "vars") from interactive_sampling().
interactive_t_test() accepts diff, sd, n, alpha and error_matrix
seed arguments, so it can be launched pre-configured like the other gadgets.
plot_regression(), plot_logit() and plot_sampling() no longer leave the
caller's par() settings modified, as CRAN Repository Policy requires. The
first two used to force par(family = "sans") rather than restoring what the
caller had set; all three now restore on exit, including when the call errors
part-way through.
plot_sampling() restores cex correctly. Its saved value was captured by
the same par() call that set mfrow, and since mfrow resets cex as a
side effect, the value it saved was already clobbered.
plot_matrix_inverse() labels its axes x and y. It built its empty
plotting region with plot(NA, ...), which deparses its first argument into
the axis labels, so the axes read Index and NA.
Every exported function now documents its return value and carries runnable
examples. Gadget examples use if (interactive()) throughout and show the
round trip from gadget to plot function.
Package prose standardized on en-US spelling; Language: en-US declared.
The README documented a visualize_inverse() function that does not exist.
Removed, and a section on reproducing an interactive session added.
plot_scatter3d() and interactive_scatter3d(): a 3D point cloud with
runtime column pickers, aspect / opacity / marker-size controls, and camera
capture so a specific rotation can be reproduced non-interactively.plot_moderation_3d() and interactive_moderation_3d() for visualizing
moderated regression as a rotatable wireframe surface.plot_moderation_3d() supports multi-predictor models; pass iv and mod to
choose which two predictors go on the plot axes.moderation_data teaching dataset.
