Just before Xmas, Conrad Sanderson released version 1.1.0 of

Armadillo, his templated C++ library

for linear algebra. Which I only noticed this week, so here comes version 0.2.11 of

RcppArmadillo, our

Rcpp-based

integration into R.

The only other change is the addition of an unexported function

`SHLIB`

which can be used to compiled a single source file into a

loadable shared library file for R, while automagically find Rcpp and

RcppArmadillo headers and the Rcpp library.

The short NEWS file extract follows, also containing Conrad’s entry for 1.1.0:

0.2.11 2011-01-06 o Upgraded to Armadillo Version 1.1.0 “Climate Vandal” * Extended submatrix views, including access to elements whose indices are specified in a separate vector * Added handling of raw binary files by save/load functions * Added cumsum() * Added interpretation of matrices as triangular via trimatu()/trimatl() * Faster solve(), inv() via explicit handling of triangular matrices * The stream for logging of errors and warnings can now be changed o New unexported R function SHLIB, a small wrapper around R CMD SHLIB, which can be used as Rscript -e "RcppArmadillo:::SHLIB('foo.cpp')"

And courtesy of

CRANberries, here is
