Open an existing HDF5 dataset

H5Dopen(h5loc, name, dapl = NULL)

Arguments

h5loc: An object of class H5IdComponent representing a H5 location identifier (file or group).
name: Name of the dataset to open.
dapl: An object of class H5IdComponent representing a H5 dataset access property list.

Value

An object of class H5IdComponent representing the opened dataset. To prevent memory leaks this must be closed with a call to H5Dclose() when no longer needed.

Examples

h5file <- tempfile(fileext = ".h5")
h5createFile(h5file)
h5createDataset(h5file, dataset = "A", dims = 10)

fid <- H5Fopen(h5file)
did <- H5Dopen(h5loc = fid, name = "A")
did
#> HDF5 DATASET 
#>         name /A
#>     filename 
#>         type H5T_IEEE_F64LE
#>         rank 1
#>         size 10
#>      maxsize 10

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