Hi Simon,
thank you for bringing this up. As mentioned in the answer to Dirk, I am at

I just build an RcppArmadillo project on my computer using gcc-4.8.1 and the

know more about my warnings:

Hi Asis,
parallel computing is a very delicate task in programming,
which depends on one side on your hardware architecture
and on the other side on your commands in your software.
1. If a sequential code is faster than the parallel code,
check if something is differently programmed or, if
Hi Asis,
I have cloned the git project and successfully installed it to R. The
'testCptsRealLive.R' does not work though. The 'load' command has problems
reading the binary file.
Nevertheless, I took a look at your OpenMP code:

in addition to what Dirk said I can tell you, that at least Armadillo Objects
do work accurate with OpenMP. I used in my code an '#pragma omp parallel for'

Isn't this actually an option when installing R

explicitly stated in the configure stage of R via --with-lapack, R uses its
internal routines.

does it reuse memory from someVector for A? From

Dear Rcpp-Devels,
I was wondering about the RNG in Armadillo (2.0 and 3.0 - functions rand and
randu). What kind of algirthm does it use? Mersenne-Twister (Seed=0)?

Dear Rcpp-Devels,
I am at a point in my project where I think intensively about best
implementation regarding performance (as my project contains Monte Carlo Markov
Chain applications at its Core - this is important).
Two facts to know about my project:

Dear Rcpp-Devels,
I am a little confused right now with the following setting:
I have a C++ class with for example the following header
#include RcppArmadillo.h
class FirstClass {
public:
Rcpp::NumericMatrix M;
FirstClass(Rcpp::S4 classS4);
in your constructor
anyway, something like:
FirstClass::FirstClass(Rcpp::S4 classS4) : M( (SEXP)classS4.slot(M_R)) {}
Hiwever, i will add the missing constructor if this does not break anything
else.
