[R-sig-hpc] Big Data packages

[Ashwin Kapur]

Just wondering if anyone has opinions on the various big data packages for R, ff vs bigmemory vs anything else.  Is anyone working on or is there already a package for connecting hdf5 to R for handling huge datasets as opposed to the hdf5 package which basically just allows you to read everything in an hdf5 at once.  I was also wondering what advantages ff/bigmemory may have to existing libraries in C for the same the most prominent of which is probably hdf5.
