R bindings for Xapian - Project progress

Hi all,

I developed the basic structure of xapian_index() function which enables
the content of a data frame to be indexed with Xapian search engine
library. I pushed it to a git repository at
https://github.com/amandaJayanetti/RXapian.
It'd be a great favour if Mr. Dirk Eddelbuettel as well as other interested
developers could kindly review the function and give me some feedback on it.

Thanks in advance,
Amanda
