R devel - Aug 2013 - Creating data.frame from c-language

I need to create a data.frame from C-language and populate it. I Know how to
create lists from C, but I cannot figure out how to create a data.frame. Does
anyone have a sample code for creating a data.frame, setting column names, and
populating it with data?

Thanks!

Use data.frame() via an eval() call from C.

Or see the code is stats/src/model.c, as part of model.frame.default 
(but I would only do that if speed were essential).
