Create a new HDF5 dataset

Usage

H5Dcreate(
  h5loc,
  name,
  dtype_id,
  h5space,
  lcpl = NULL,
  dcpl = NULL,
  dapl = NULL
)

Arguments

h5loc: 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.
name: Name of the dataset.
dtype_id: A character name of a datatype. See h5const("H5T") for possible datatypes. Can also be an integer representing an HDF5 datatype.
h5space: An object of class H5IdComponent representing a H5 dataspace. See H5Dget_space(), H5Screate_simple(), H5Screate() to create an object of this kind
lcpl, dcpl, dapl: An objects of class H5IdComponent representing HDF5 property lists. Specially these should respectively be: a link creation property list, a dataset creation property list, a dataset access property list

Value

An object of class H5IdComponent representing the opened dataset.

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")
did
#> HDF5 DATASET 
#>         name /A
#>     filename 
#>         type H5T_STD_I32LE
#>         rank 1
#>         size 10
#>      maxsize 10

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