mvpart 1.6-4

This fork (aurelienboye/mvpart)

• Patched the C source so the package compiles on modern R, confirmed working on:
  • macOS, R 4.6.1
  • Windows, R 4.5.1 and R 4.6.1 (Rtools45/46)
  • Linux (Ubuntu, via GitHub Actions)
• Root cause: several old C constructs (empty-parameter function pointer declarations, K&R-style function definitions, removed S-compatibility macros/types) that R’s headers used to tolerate are rejected under the C23 standard R 4.5+ selects by default on Windows. Fixes were prototype/declaration additions or macro renames; two genuine latent type-mismatch bugs were also found and fixed (s_xpred.c, xval.c), confirmed to have zero effect on results.
• No changes were made to the package’s statistical logic.
• Added a worked-example vignette (mrt-worked-example), using the Doubs fish dataset, demonstrating a full MRT workflow together with MVPARTwrap.

About MVPART

The mvpart package is a modification of rpart:

• Authors of the original rpart: Terry M. Therneau and Beth Atkinson (atkinson@mayo.edu).
• R port of rpart: Brian Ripley (ripley@stats.ox.ac.uk).
• Modifications from rpart to mvpart: Glenn De’ath (g.death@aims.gov.au).

mvpart includes partitioning based on (1) multivariate numeric responses and (2) dissimilarity matrices. It was not possible to build a separate package depending on rpart, owing to the modifications needed in rpart’s C code to support these two new partitioning methods — as few changes as possible were made to rpart itself.

In addition to the C-code changes, the following changes and additions were made to the R functions:

1. A wrapper function for rpart, called mvpart, supporting selection of trees by cross-validation, interactive display, printing of results, etc.
2. Multivariate methods for representing and interpreting multivariate partitioning objects, including PCA plots and tree-cluster comparisons.
3. Methods for calculating additional forms of dissimilarities and for scaling matrices, designed in particular for community ecology.
4. text.rpart was modified to include graphical annotation of nodes.
