An alternative R package for accessing HDF5 file format.
Objective: To enable the fully compatable data exchange between Python's Pandas data frames and R's data frames. Background: The currently most popular rhdf5 package http://www.bioconductor.org/packages/release/bioc/html/rhdf5.html can not handle data types other than numeric matrix and string. That makes it impossible to read and write data type such as datetime, factor from HDF5 files.
