Additional functions for finding details of dataset chunking.

Usage

H5Dchunk_dims(h5dataset)

H5Dis_chunked(h5dataset)

Arguments

h5dataset

Object of class H5IdComponent representing an open HDF5 dataset.

Value

  • H5Dchunk_dims: If the supplied dataset is chunked returns a vector, with length equal to the rank of the dataset, containing the size of the dataset dimensions. Returns NULL if the given dataset is not chunked.

  • H5Dis_chunked: returns TRUE if a dataset is chunked and FALSE otherwise.

Details

These functions do not map directly to the HDF5 C API but follow the same style and are included as potentially useful additions.

  • H5Dis_chunked tests whether a dataset is chunked.

  • H5Dchunk_dims will return the dimensions of the dataset chunks.
