[R] Using sample() twice (bootstrapping from > 1 vector)

I am using sample() to take bootstrap replicates and want to be able to
take replicates from multiple columns in a data.frame. I have done this
by using set.seed() to set the seed to the replicate number:

        for(i in i:10) {
          x <- sample(...
          y <- sample(...
prior to the call to sample(). Is there a better way of doing this? Any
way of getting rid of the for() loop?
