Earlier today, Conrad has released 3.3.91 aka "v3.4 beta 1", which I wrapped
into RcppArmadillo 0.3.3.91. The NEWS entry below details some of the
changes (performance gains, beginning sparse matrix support, small
enhancements to fastLm).
Because CRAN now prefers to get only about one upload per package and month,
I am not pushing this release there. You can get it from R-Forge via SVN, via
a tarball (once built, I believe this is a once-a-day cron job) or via
install.packages("RcppArmadillo", repos="http://R-Forge.R-project.org") once
the tarball is there. It's also in http://dirk.eddelbuettel.com/code/rcpp/

algorithm
