# 
Instead of a loop you can use the replicate or lapply functions which
will create lists for you.

otherwise you can start with an empty list (mylist <- list() )

then add to the list in each iteration of the loop:

for(i in 1:10) {
    mylist[[i]] <- myfunction(i)
}

Hi,

Try this,

list1<-list()
vec<-rnorm(15,25)

for(i in 1:20)
{
list1[[i]]<-sample(vec,replace=FALSE)
}
list1
