subsampling

hi, I would like to subsample the array c(1:200) at random into ten subsamples v1,v2,...,v10.
(Why are you c()'ing a single vector?)
I tried with to go progressively like this:
x<-c(1:200) v1<-sample(x,20) y<-x[-v1] v2<-sample(y,20)
and then I want to do:
x<-y[-v2]
Error: subscript out of bounds.
That's not going to work (hint, the values contained in y do not correspond to their indices). I'd just do split(sample(1:200),rep(1:10,each=20))
