New RcppArmadillo relase(s) -- I just posted the following (with proper
links and highlighting) to
In short, a new RcppArmadillo is on CRAN, and an even newer is available via
a drat repo. See other recent posts on my blog about drat -- a helpful new tool.

RcppArmadillo 0.4.650.1.1 (and also 0.4.650.2.0)
A new Armadillo release 4.650.1 was released by Conrad a few days ago.
Armadillo is a powerful and expressive C++ template library for linear
algebra aiming towards a good balance between speed and ease of use with a
syntax deliberately close to a Matlab.
It turned out that this release had one shortcoming with respect to the
C++11 RNG initializations in the R use case (where we need to protect the
users from the C++98 RNG deemed unsuitable by the CRAN gatekeepers). And
this lead to upstream release 4.650.1 which we wrapped into RcppArmadillo
0.4.650.1.1. As before this, was tested against all 107 reverse
dependencies of RcppArmadillo on the CRAN repo.
This version is now on CRAN, and was just uploaded to Debian. Its changes
are summarized below based on the NEWS.Rd file.
Changes in RcppArmadillo version 0.4.650.1.1 (2015-02-25)
* Upgraded to Armadillo release Version 4.650.1 ("Intravenous Caffeine
* added randg() for generating random values from gamma
distributions (C++11 only)
* added .head_rows() and .tail_rows() to submatrix views
* added .head_cols() and .tail_cols() to submatrix views
* expanded eigs_sym() to optionally calculate eigenvalues with
smallest/largest algebraic values fixes for handling of sparse
* Applied small correction to main header file to set up C++11 RNG
whether or not the alternate RNG (based on R, our default) is used
Now, it turns out that another small fix was needed for the corner case of
a submatrix within a submatrix, ie V.subvec(1,10).tail(5). I decided not
to re-release this to CRAN given the CRAN Repository Policy preference for
releases "no more than every 1-2 months".
But fear not, for we now have drat. I created a drat package repository in
the RcppCore account (to not put a larger package into my main drat
repository often used via a fork to initialize a drat). So now with these
two simple commands
## if needed, first install 'drat' via: install.packages("drat")
you will get the newest RcppArmadillo via this drat package repository.
And course install.packages("RcppArmadillo") would also work, but takes
longer to type :)
Lastly, courtesy of CRANberries, there is also a diffstat report for the
most recent CRAN release. As always, more detailed information is on the
RcppArmadillo page. Questions, comments etc should go to the rcpp-devel
mailing list off the R-Forge page.
