Representation of HDF5 dataset to be used instead of an R array
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.
