DataFrames was written with the intent that columns are vector-like objects. Sometimes other objects can be used, but support of features gets iffy. Options that might work include:
* Wrap your multidimensional object in a vector type that returns the appropriate subset when indexed by a row. That will work with the existing DataFrames. * Submit a pull request to DataFrames to better support multidimensional objects.
