Representation of HDF5 dataset to be used instead of an R array
hdf5_matrix(datapath, dataset, start = 0, end = NULL, normalizer = NULL)
An array-like HDF5 dataset.
string, path to a HDF5 file
string, name of the HDF5 dataset in the file specified in datapath
int, start of desired slice of the specified dataset
int, end of desired slice of the specified dataset
function to be called on data when retrieved
Providing start
and end
allows use of a slice of the dataset.
Optionally, a normalizer function (or lambda) can be given. This will be called on every slice of data retrieved.
