HDF5 compound data types and h5r/hdf5 R packages
...group "yyy" {
dataset {}
dataset {}
}
group "zzz" {
dataset {}
dataset {}
}
}
where dataset is a rank one dataspace having a compound datatype defined as:
H5T_UNIX_TIME, float, float, float, float
I have tried R packages h5r and hdf5 in an attempt to read the file
but examining the source of h5r and reading documentation for hdf5
here: http://xweb.geos.ed.ac.uk/~hcp/Rhdf5.html leads me to believe
that compound datatypes are not supported by these packages. My guess
is that mapping arbitrary type definitions in HDF5...

best HDF5 package: h5r or rhdf5?
What is the current best package for manipulating HDF5 data files?
I tried "hdf5" a long time ago, but I ran into memory problems. "h5r" is on
CRAN now, and "rhdf5" is part of bioconductor.
Ideally, I'd like to read simple vectors or tables, either the entire thing
or a subset of rows. I don't need much writing support, but it would be
nice. Compression is a must, though.
Thanks,
Johann
