It is more complicated than that see:
http://code.google.com/p/sqldf/
It is a framework sqldf over a framework rsqlite over sqlite. The data frames
the OP is talking about are variables that are coerced to being 'tables'. I can
see no mailing list for sqldf itself. The closet I could come is
https://stat.ethz.ch/mailman/listinfo/r-help
which seems to have quite a few discussions on sqldf and would probably be the
better place to ask this question.
