I have tried with the following, but just compute the second argument of the body, i.e., the summary:

Hi Manuel,

In addition to my fellow R-helpers:

R does not save the result of the apply function on x. Now you calculate 
it and it is discarded. To save it, try something like:

resumen<-function(x) {
	y = apply(x,2,sd,na.rm=TRUE)
	summary(y)
	}

Or print statements on both lines, as the others suggested.

cheers,
Paul
