Parallel processing for R loop
3 messages · Sandeep Patil, Eik Vettorazzi, Paul Hiemstra
Hi Sandeep, still missing an answer? Perhaps you cross check your post with the rules of the posting guide and find what is missing at all here. Anyway, depending on your OS, package multicore, snow/snowfall may fit your needs - but you have to re-formulate your loop using adequate multicore *apply-functions. hth Am 11.10.2011 14:13, schrieb Sandeep Patil:
I have an R script that consists of a for loop that repeats a process for many different files. I want to process this parallely on machine with multiple cores, is there any package for it ? Thanks
