Not an R package, but EpiData is free software designed to to exactly this.
It's a wonderful piece of software. Define fields, add annotations, provide
defaults, provide allowable values or ranges, calculate one field based on
entry to another, conditional skipping from one question to another depending
on answer, relational database capaability, double-entry verification, and
more. I don't think it exports directly to Rdata format, but it can export to
plain text, SAS, Stata, dBase, and Excel, any of which I think can be read into
R.
