Thanks for your reply. In fact my code example was simplified from
something more general
for (i in 2:length(w[,1])) {
w[i,] <- foo( w[i-1,] )
}
and I was trying to write this without a loop. I will look at the
method you describe, but I'm not sure if it can still be applied if
foo() is quite complex. (sorry for sending this to the wrong list, I
thought this one was about everything that can make R running faster!)
Cheers
Guillaume
