Bug Fixes

• Fixed reconstruct_new.bi_projector() double-preprocessing bug that caused incorrect reconstruction when applied to held-out data.

Vignette Improvements

• Rewrote CrossValidation vignette with working examples (fixed broken reconstruct() usage and results extraction).
• Cleaned up PermutationTesting vignette: improved structure, replaced dense tables with readable prose.
• Cleaned up Regress vignette: broke up long code block into focused subsections.

• Fixed bootstrap.plsc() duplicate argument handling when called with named X/Y arguments.
• Fixed regress() PLS method dimension mismatch.
• Fixed iris data frame to matrix conversion in examples.

Internal Changes

• Registered S3 methods: classifier.projector, inverse_projection.projector, perm_ci.pca.
• Added missing importFrom directives for coefficients and combn.
• Replaced non-ASCII characters with ASCII equivalents in documentation.

Deprecated
