hdf5_matrix(datapath, dataset, start = 0, end = NULL,
  normalizer = NULL)

Arguments

datapath

string, path to a HDF5 file

dataset

string, name of the HDF5 dataset in the file specified in datapath

start

int, start of desired slice of the specified dataset

end

int, end of desired slice of the specified dataset

normalizer

function to be called on data when retrieved

Value

An array-like HDF5 dataset.

Details

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.
