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().
