This directory contains R scripts that demonstrate the "multicore" package, and are based on examples in chapter three of the book "Parallel R". The example scripts can be executed using a command such as: % R --slave -f mclapply.R or using the "source" function within an R session: > source('mclapply.R') Example scripts: mclapply.R Using mclapply to implement parallel kmeans mccores.R The mc.cores argument mcsetseed.R The mc.setseed argument mcpreschedule.R The mc.preschedule argument mcpvec.R Example use of the pvec function mcparallelcollect.R Example use of the parallel and collect functions mcrng.R Using a parallel RNG with multicore mclowlevel.R Using the low-level API to implement a stripped- down version of the mclapply function.
