Write data to dataset

Usage

H5Dwrite(h5dataset, buf, h5type = NULL, h5spaceMem = NULL, h5spaceFile = NULL)

Arguments

h5dataset: Object of class H5IdComponent representing an open HDF5 dataset.
buf: The R object containing the data to be written to the dataset.
h5type: Datatype of the HDF5 dataset to be written. If left as NULL it will use the dataype of the R object supplied to buf.
h5spaceMem, h5spaceFile: H5IdComponent objects representing the memory and file dataspaces respectively. If these are left NULL dataspaces that match the size and shape of h5dataset will be used.

Examples

h5file <- tempfile(fileext = ".h5")
h5createFile(h5file)

fid <- H5Fopen(h5file)
H5Dcreate(h5loc = fid, name = "A", dtype_id = "H5T_NATIVE_INT", h5space = H5Screate_simple(10))
did <- H5Dopen(h5loc = fid, name = "A")
H5Dwrite(h5dataset = did, buf = 1:10)
H5Dread(did)
#>  [1]  1  2  3  4  5  6  7  8  9 10

## remember to close open handles
H5Dclose(did)
H5Fclose(fid)
