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.
