 always reversing the dimensions
that are passed between R and HDF5 and therefore making the distinction
transparent. For arrays, this is however a bit trickier. For example let
us assume that we have a dataset that is a one-dimensional vector of
length 10, each element of which is an array-datatype of length 4,
resulting in a 10 x 4 dataset. However, it is now not quite clear how
this should be represented in R. If we follow the notion, that the
fastest changing dimension in R is the first one, the result
