eral, R numerical objects are either represented as
64-bit floating point values (doubles) or 32-but integers. R switches
relatively transparently between these types as needed (for
computations, integers are converted to doubles and conversely, array
positions can be addressed by doubles). The main issue when working with
HDF5 occurs as R doesn’t have either a 64bit signed or unsigned integer
datatype (and also not a long double). In order to work around this
issue, the following conventions are being us
