Tobias,
I'm not sure if this is what you're after, but perhaps it will help.
# create a list of 5 vectors
n <- 5
subsets <- lapply(1:n, function(x) rnorm(5, mean=80, sd=1))
# create another list that takes 2 bootstrap samples from each of the 5
vectors and puts them in a matrix
nbootstrap <- 2
test <- lapply(subsets, function(x) matrix(sample(x, nbootstrap*length(x),
replace=TRUE), ncol=nbootstrap))
subsets
test
