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().

Emne: [R] multicore combn
This is a 'rather than re-invent the wheel' post. 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. Thanks!
