IBM® BigInsights® Big R is a library of functions that provide end-to-end integration with the R language and BigInsights. Big R can be used for comprehensive data analysis on the BigInsights server, hiding some of the complexity of manually writing MapReduce jobs. You must download, license, and install the appropriate R software before using Big R.

In an R environment you can use both R and Big R functions to perform comprehensive data analysis on big data hosted on an IBM BigInsights cluster. Big R functions are similar to existing R functions, but are able to scale for use with big data.
