A new release 0.3.3.9.4 of RcppEigen arrived on CRAN yesterday, and went to Debian today. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms. This update contains a small amount of the usual maintenance (see below), along with a very nice pull request by Mikael Jagan which simplifies to interface with the Matrix package and inparticular the CHOLMOD library that is part of SuiteSparse. This release is coordinated with lme4 and OpenMx which are also being updated. The complete NEWS file entry follows.

A new maintenance release 0.3.2.9.1 of RcppEigen, still based on Eigen 3.2.9 is now on CRAN and is now going into Debian soon. This update ensures that RcppEigen and the Matrix package agree on their #define statements for the CholMod / SuiteSparse library. Thanks to Martin Maechler for the pull request. I also added a file src/init.c as now suggested (soon: requested) by the R CMD check package validation. The complete NEWS file entry follows.

Changes in RcppEigen version 0.3.2.9.1 (2017-03-14)

• Synchronize CholMod header file with Matrix package to ensure binary compatibility on all platforms (Martin Maechler in #42)
• Added file init.c with calls to R_registerRoutines() and R_useDynamicSymbols(); also use .registration=TRUE in useDynLib in NAMESPACE
