[R] multicore combn

[Søren Højsgaard]

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().

Regards
Søren

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!
