Changes in version 0.4.3.9000                      

                 Changes in version 0.4.3 (2025-12-17)                  

  - Remove dependency on gghalves. In plot_correlation_counts(), remove
    half_violin argument, and replace with points argument, which adds
    jittered points on top of the violin.

                 Changes in version 0.4.2 (2025-12-04)                  

  - In plot_pc_vs(), allow unicode letter class and mark combinations in
    variable names
  - More detail provided for article on use of rotations.
  - Remove dependency on vegan::procrustes()
  - Fix typo in plot_correlation_counts()
  - Switch to institutional email due to unreliability of previous email
    and consequent archiving of 0.4.1.

                 Changes in version 0.4.1 (2025-05-06)                  

  - Remove VignetteBuilder from DRESCRIPTION.
  - Now plot_procrustes_loadings() correctly sets the y-axis label to
    'Loading' or 'Index loading'.

                        Changes in version 0.4.0                        

Breaking changes

  - In mds_test(), first argument changed from similarity_matrix to
    dissimilarity_matrix to match the behaviour expected by users of
    smacof::smacofSym()

New features

  - 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.

                 Changes in version 0.3.1 (2024-11-29)                  

  - Documentation fixes to initial CRAN submission (nzilbb.vowels 0.3).

                         Changes in version 0.3                         

  - Initial submission to CRAN
  - mds_test() and plot_mds_test() added to determine number of
    dimensions for MDS.
  - pc_flip() added to reverse orientation of selected PCs in PCA
    analysis.

                        Changes in version 0.2.1                        

  - All functions required for Wilson Black et al. (2022)
