half_violin argument, and replace with points argument, which adds jittered
points on top of the violin.plot_pc_vs(), allow unicode letter class and mark combinations in
variable namesvegan::procrustes()plot_correlation_counts()VignetteBuilder from DRESCRIPTION.plot_procrustes_loadings() correctly sets the y-axis label to 'Loading'
or 'Index loading'.mds_test(), first argument changed from similarity_matrix to
dissimilarity_matrix to match the behaviour expected by users of
smacof::smacofSym()New pca_rotate_2d() takes the output of stats::prcomp() or
stats::princomp() and rotates two specified PCs clockwise by angle degrees.
Both scores and loadings are rotated and the variance explained by each
component is updates.
New pca_rotate_procrustes() allows Procrustes rotation of the output of
prcomp() or princomp() to match a target configuration of either scores
or loadings. Partial overlap of variables is enabled by rotation_variables.
Both scores and loadings are rotated and the variance explained by each
component is updates.
New procrustes_loadings() generates data to enable calculation of
confidence intervals of loadings, or confidence intervals and null distributions
of index loadings, by bootstrapping, permutation, and Procrustes rotation.
New plot_procrustes_loadings() provided to plot the output of
procrustes_loadings().
New articles on package website https://nzilbb.github.io/nzilbb_vowels/ covering the 'model-to-PCA' workflow used at NZILBB and the use of rotation with PCA.
