Integrative Analysis of Several Related Data Matrices
Back from CRAN removal under a new maintainer, with the compiled layer rebuilt.
cranmaintainershiprcppbuild-systemmatrix-decomposition
◆Current state
mmpca implements multiple matrix principal component analysis with a compiled GSL backend. The package spent time off CRAN, and its recent history is a rescue operation rather than a feature program: a new maintainer took it over, moved the native build path onto RcppGSL, and folded the hand-written C bindings into Rcpp. The two most recent entries landed the same day, one restoring the package and one clearing residual CRAN comments.
◆Where it's heading
Work is concentrated on making the package installable and check-clean rather than on the decomposition itself. The version stamps run out of order, with 2.0.3 predating both 2.0.2 and 2.0.4 by three years, so the feed reads as an archive flush around the CRAN return. Nothing in the entries points at method-level work.
◆Prediction
Expect maintenance releases that keep the compiled code passing CRAN checks; the entries give no signal about new decomposition features.

Back on CRAN under a new maintainer, rebuilt on RcppGSL
⚡ SPARKThe release that put mmpca back on CRAN under a new maintainer, with autoconf replaced by RcppGSL and the mixed C/C++ binding layer consolidated on Rcpp. It restores distribution rather than adding capability.

Valgrind memory fixes and a maximum-iteration option
Predates the CRAN rescue by three years: Valgrind-flagged memory issues fixed and an iteration cap exposed in the optimizer. The user-visible part is the new control over how long fitting runs.
