This looks like the notorious 7.31 FAQ, and has been asked in the same
context already on this list (but the author did not believe it).

7.31 Why doesn't R think these numbers are equal?

Try to replace your 3.50000 and 4.5000 by 3.5001 and 4.5001 or (3.4999 and
4.4999); if things work after that, 7.31 hit again. If not, my guess was
wrong.
