Just thought I'd let you know the following: In the gRbase package there is a function called combnPrim which does the same as combn but it is implemented in C - and is quite a bit faster than combn().

Has anyone out there re-written combn so that it can be parallelized - with multicore, snow, or otherwise? I have a job that requires large numbers of combinations, and rather than get all of the index values, then crank it through mclapply, I was wondering if there was a way to just do this natively within a function. Just curious.
