robCompositions 2.6.0

• imputeBDLs() has been renamed to imputeBDL(). imputeBDLs() is kept as a deprecated alias and will be removed in a future release.
• impRZilr() is deprecated and is now an alias of imputeBDL() (the same method: EM-based replacement of rounded zeros in pivot coordinates). Its results are unchanged; please switch to imputeBDL().
• imputeBDL() now correctly imputes values below the detection limit even when they are supplied as small positive numbers rather than exact zeros. Earlier imputeBDLs() silently skipped such values because the checkData() thresholding result was discarded. Results for the documented usage (rounded zeros pre-coded as 0) are unchanged.
• impAll() no longer returns NULL for data containing rounded zeros (it read a list element that no longer exists); it now calls imputeBDL() internally.
• removed a stray diagnostic print() from the rounded-zero imputation, a duplicate internal impAll() definition, and broken non-default code paths (the 'test' argument of imputeBDLs() and the unused 'variation' branch of impRZilr()).
• imputeUDLs() now returns an object of class "replaced", and the imputed-zero index ('wind') of imputeBDL()/imputeUDLs() is returned aligned with the original column order.

robCompositions 2.5.0

• new function cellPcaCoDa() for cellwise-robust PCA of compositional data, with print/summary/plot methods, implementing Templ (2026, Advances in Data Analysis and Classification)
• new function contaminate_simplex() to generate cellwise-contaminated compositions
• cellPcaCoDa() defaults now follow the paper: Tukey biweight loss and MCD initialisation (new 'init' argument); the cellwise detection step uses the standardised projection test. Default-path results therefore differ from earlier development versions.
• cellPcaCoDa() now requires at least 3 parts (D >= 3) and warns when k = D-1, where the residual space is empty and cellwise detection is disabled (use k < D-1).
• cellPcaCoDa() detects period-2 limit cycles in the alternating scheme and stops at the stabilised cycle (new 'cycled' flag in the result) instead of running to maxiter.
• ggplot2, pls and data.table moved from 'Depends' to 'Imports' (they are no longer attached to the search path; load them explicitly if your own code relied on that attachment)
