hmr - Hadoop Map/Reduce package for R

High-performance Hadoop Map/Reduce R interface based on iotools. Main feature is the use of chunk-wise processing and automatic conversion to/from R objects as to make it very easy for users to run existing R code on Hadoop while providing much higher performance than "classic" key/value operations as used in other packages like rmr.

For high-level discussion see the iotools Wiki

The main package webpage is on RForge.net and you can install hmr from latest sources using

install.packages("hmr",,"http://rforge.net")

in R. The RForge.net repository is updated on every commit.
