How it works...
Besides writing an R MapReduce program using the rmr2 package, you can use the plyrmr to manipulate data. The plyrmr package is similar to hive and pig in the Hadoop ecosystem, which is the abstraction of the MapReduce program. Therefore, we can implement an R MapReduce program in plyr style instead of implementing the map and reduce functions.
To install plyrmr, first install the package of libxml2-devel and curl-devel, using the yum install command. Then, access R and install the dependent packages. Lastly, download the file from GitHub and install plyrmr in R.
