Dear Dirk, Doug, and Romain,
Thanks a lot for your (very fast ---didn't even have time to have dinner
;-) responses. I was aware of the column-major order in R, but for no
reason I was expecting row-major in C++ (but then, I was expecting nrow
and ncol to work as they did).
I'll play around wit
Hi Ramon,
And welcome!

In short: No.
In more detail, and allow me to quote from Section "5.11.2 Calculating
numerical derivatives" in "Writing R

Rcpp plays with the rules set by R. And R says : column major.
I thought tha
An Rcpp object uses the storage allocated in R hence it has the same
column-major ordering of the elements in a matrix. The same is true of
matrix objects in RcppArmadillo.
Basically anything that uses Lapack and BLAS or calling sequences
compatible with Lapack or BLAS uses column-major ordering.
Dear All,

I thought that, for any of the Matrix types available, if we have
x(i, j)
then
x(i, j + 1)
would be contiguous in memory (whereas x(i

Yes, I already did that, but I didn't try because your first answer (and
because I need to upgrade ...).
I'll tell you about improvements.
Thank you again Dirk.

Hello Romain,
I thought linking to libR would be all that is needed.
I have installed RInside, got the example code compiled and substituted my
function and it compiled and run.
Thanks a lot for the help!

Hello,
Rcpp is for calling C++ code from R. Why did you think you can use it
without R ?
Have a look at RInside, which will let you embed R in a c++ application.
But no miracle there either, you will still need R.
