Thanks to all of you for those answers, it now works and it's way faster
than it used to be ;)
Especially, converting my list of matrix to a 3-dimensionnal array
simplifies a lot the statistics I have to run on my data :)
Thanks again,
Robin

Hi robin,
I'm not sure is what you need, but that's an esthetically nice
solution (one single line without any loop :) )
matrix(apply(log(cbind(as.numeric(a),as.numeric(b),as.numeric(c),as.numeric(d))),1,sd),3)
hope it could help,

Hello,
I'm currently trying to convert a slow and ugly script I made, so that
it's
faster and can be computed on a computer grid with the multicore
package.
My problem is that I don't see how to turn some loops into an
apply-able
function.

Here's an example of my loops :
