[R] How to read a specific dataset, not the entire data, from HDF5?

[Daehyok Shin]

Thanks, Felix.
You are watching new questions here.
I will give a try to rgdal and let you know the result.
BTW, it is surprising to me that there seems no R package handling
HDF5 like PyTables does for Python community, considering HDF5 is as
popular as NetCDF as a file format for scientific data. I hope the gap
will be filled in near future.

DH
