New RcppArmadillo relase(s) -- I just posted the following (with proper
links and highlighting) to
http://dirk.eddelbuettel.com/blog/2015/02/26#rcpparmadillo_0.4.650.1.1
In short, a new RcppArmadillo is on CRAN, and an even newer is available via
a drat repo. See other recent posts on my blo

I thought I'd step in and grab this one :)
"In general, it's certainly a reasonable point that there is a trade-off
to be made -- user-friendliness against the potential extra copies (not
sure whether this has ever been measured -- as in counting the cases of
`clone`-less existing code-bases where

Thanks, it works!
I'm not familiar with C++, is it necessary to always use such a
function in C++ or is it because of R/C++ interface?
Hi Pierre!
You're witnessing yet another fascinating difference between (usual in
the world of C++) value semantics
Ok, i'll do this.
Thanks and have a nice day,

Please use a Google search (or equivalent) for Rcpp::clone. This has been
discussed extensively on nu

Hello everybody,
I have a very simple example
I have a vector vec_CMA which length is a multiple of 6.
I want to get the exact same vector, except the last element which is
the exponential of the last element of vec_CMA
The code is the following
//myfun.cpp
#include
using namespace Rcpp;
//
11 matches
