[R] multicore by(), like mclapply?

[Matthew Dowle]

Package plyr has .parallel.

Searching datatable-help for "multicore", say on Nabble here,

http://r.789695.n4.nabble.com/datatable-help-f2315188.html

yields three relevant posts and examples.

Please check wiki do's and don'ts to make sure you didn't
fall into one of those traps, though (we don't know data or task so
just guessing) :
