>From the help for data.frame() (sic):
Objects passed to 'data.frame' should have the same number of
rows, but atomic vectors, factors and character vectors protected
by 'I' will be recycled a whole number of times if necessary.
so this is the documented behaviour.
Perhaps you meant this for the wishlist, but you did not follow the
instructions in the FAQ for sending it there. Nor is there any case made
for why this would be desirable (and second-guessing the user's intentions
often is not).
I'll place it on the wishlist, but personally think it would be
undesirable to add such an inconsistency to the language.
