 Thanks Martin, that sounds great.

 This came about from a question on Stack Overflow, where a user was
loading an R Data file and seemingly there was nothing in it, and
there were no warnings. I suspected maybe there really was nothing in
it, and discovered an easy way to create empty R Data files without
really trying.

 Turns out her file was over 400k bytes long and once she reinstalled
R [yikes] it loaded... What was the real problem? Well we never found
out!
