## Create HDF5 group

### Description

Creates a group within an HDF5 file.

### Usage

    h5createGroup (file, group)

### 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.
`group` | The name of the new group. The name can contain a hierarchy of groupnames, e.g. 'group1/group2/newgroup', but the function will fail if the top level group do not exists.

### Details
