<p>I have a wrapper python script that used RPy2 and I am calling native R functions and script, but I want to run R in a multithreaded environment. At the moment I am able to run R in multi process mode. Any ideas how this can be done?</p>

See <a href="http://stackoverflow.com/questions/17196261/understanding-the-differences-between-mclapply-and-parlapply-in-r">here</a>, question I asked on stackOverflow a while ago.
