<dt>dims</dt>
<dd><p>Dimension of the new dataset; used if <code>space</code> is <code>NULL</code>. overwrite the dimension guessed from <code>robj</code>
if <code>robj</code> is given.</p></dd>

<dt>chunk_dims</dt>
<dd><p>Size of the chunk. Has to have the same length as the dataset dimension. If <code>"auto"</code>
then the size of each chunk is estimated so that each chunk is roughly as large in bytes as the value in
the <code>hdf5r.chunk_size</co
