====== hdf5 ======

**hdf5** is a software module available on **Comet**.

<WRAP round box tip>
If you are intending to use HDF5 within R, be aware that due to practical limits of the size of the library path __not__ all module library paths are added by default. If you are compiling R libraries which need HDF5, then you will need to extend your **LD_LIBRARY_PATH** for any additional system libraries (HDF5, Szip, etc) that your R library needs. Please take a look at how to extend your library search path within an R or R-Studio environment:
