rhdf5 (version 2.16.0)

h5set_extent: Set a new dataset extension

Description

Set a new dataset extension to an existing dataset in an HDF5 file

Usage

h5set_extent(file, dataset, dims)

Arguments

file

The filename (character) of the file in which the dataset will be located. For advanced programmers it is possible to provide an object of class H5IdComponent representing a H5 location identifier (file or group). See H5Fcreate, H5Fopen, H5Gcreate, H5Gopen to create an object of this kind.

dataset

The name of the dataset in the HDF5 file, or an object of class H5IdComponent representing a H5 dataset identifier. See H5Dcreate, or H5Dopen to create an object of this kind.

dims

The dimensions of the array as they will appear in the file. Note, the dimensions will appear in inverted order when viewing the file with a C-programm (e.g. HDFView), because the fastest changing dimension in R is the first one, whereas the fastest changing dimension in C is the last one.
