I just want to understand: do you mean namespaces to be used within an R2RML file or namespaces and prefixes in the generated file?

I am not sure I understand the need for the former; I suspect this is not what you meant.

As for the latter: my understanding is that R2RML defines a way to generate RDF triples from tables. I mean: RDF triples in the abstract, conceptual sense, and not in any particular serialization. On the other hand, the usage of prefixes/namespaces is a matter of a particular serialization; I am not sure it has a place in R2RML...

But I may completely misunderstand you!
