Actually I am trying my level best to integrate with R, but I got this error.
packages ‘rmr’, ‘rJava‘, ‘RJSONIO‘, ‘rhdfs’, ‘rhbase’, ‘plyrmr’ are not available (
You can download the packages from CRAN's website and install them without connecting to the repository.
For example, to download 'rJava' package, you can visit this link: http://cran.r-project.org/web/packages/rJava/index.html
From there, download the 'Package source', and install them manually like this:
install.packages('path to downloads/rJava_0.9-6.tar.gz',repos=NULL)
You can follow the same pattern for the other mentioned packages. The rhdfs, rhbase and rmr packages are located at https://github.com/RevolutionAnalytics/RHadoop/wiki/Downloads
