Conrad Sanderson released version 1.99.5 of Armadillo yesterday. This provides the fifth release candidate en route to version 2.0.0. He was even kind enough to post on rcpp-devel about it too as it entails some minor API changes. His version 1.99.5 has been integrated into RcppArmadillo version 0.2.23 which is now on CRAN. By way of background, Armadillo is a templated C++ library for linear algebra---which RcppArmadillo brings to R based on our Rcpp library.

A minor internal change was the rearrangement of arguments for the (mostly internal) function fastLmPure so that it is closer to the R function lm.fit which it mimics. The user-facing function for fastLm, using either the formula method or the default method, have not changed.

The short NEWS file extract follows below. I also include the entry for the bugfix release 0.2.22 (based on Armadillo 1.99.4) which preceded it, and which does not seem to have gotten its own blog post.

0.2.23  2011-05-23

    o   Upgraded to Armadillo release 1.99.5 "v2.0 beta 5"

          * Forms of chol(), eig_sym(), eig_gen(), inv(), lu(), pinv(),
	    princomp(), qr(), solve(), svd(), syl() that do not return a bool
	    indicating success now throw std::runtime_error exceptions when
	    failures are detected 
          * princomp_cov() has been removed; princomp() in conjunction with
	    cov() can be used instead
          * set_log_stream() & get_log_stream() have been replaced by
	    set_stream_err1() & get_stream_err1()
          * det(), inv() and solve() can be forced to use more precise
	    algorithms for tiny matrices (≤ 4x4)
          * Added loading & saving of matrices as CSV text files 

    o   fastLmPure() now uses same argument order as R's lm.fit()

    o   Export and document S3 methods in NAMESPACE and manual page as such

0.2.22  2011-06-06

    o   Upgraded to Armadillo release 1.99.4 "v2.0 beta 4" 

          * fixes for handling of tiny matrices
