The upcoming upgrade to Armadillo (version 3.2) will have a bunch of
speedups, including faster eigen-decomposition.
Armadillo 3.2 is currently in beta testing.

There is a dedicated mailing list for Rcpp: rcpp-devel.
Please let us try to continue the di

I do not think you will get '2x'. I'd say between 1/5 to 1/3.
Not neglible, but not earth-shattering given that
a) Armadillo is easier to work with (IMHO, and personal taste) and
b) yo

Hi,
I am using a Makevar file for Rcpp package. It's from [
Rcpp.package.skeleton( ) ] command.
I added something for GSL.
GSL_CFLAGS = `gsl-config --cflags`
GSL_LIBS = `gsl-config --libs`
PKG_CXXFLAGS= `${R_HOME}/bin/Rscript -e "Rcpp:::CxxFlags()"` $(GSL_CFLAGS)
PKG_LIBS = `$(R_HOME)/bin/Rsc
Thanks for that. So, roughly 2x vs arma for lm fit.
It would not be hard to test it on my logp functions in cppbugs...
Perhaps after R/Fin. I'll post back once I get around to it. Thanks again.
Cheers,

Doug,
Apologies for my question, it's a little off topic from your original
post (hence the modified subject).
I've integrated Armadillo into the new mcmc packages I've been
developing without giving much thought to Eigen.
Unfortunately, the benchmarks page on the Armadillo site doesn't
provide
Thank you for your prompt response!
Sorry, this was more a C++ question. I'm still having a hard time to
disentangle all of these methods and languages.
It worked! I have included below the .R, .h, and .cpp files of the fx
from my previous e-mail. Just to help the next newbie ;) .
Thanks!
