wrong place for this question, should go to r-help at r-project.org

anyway, i am not aware any R-function that gives all subsets of size k. i
will use matlab to create it and input it back to R if you don't want to
stick with matlab for the rest.

if you have some time to spare, you can create your own function by
implement the algorithms that generates all subsets of size k. a good
source for such algorithms is http://www.cs.sunysb.edu/~algorith/

good luck
