Hi
Well, I cannot help you any further. It can be platform or version issue. You are using Mac, I work with PC, your R version is 3.2.1 mine is 3.3.0 (devel). Wizards from R core are appropriate for answering this. You can transfer our conversation to R-sig-Mac, if people using Mac found similar issue as you.
If there is R-devel for Mac you can try to install it and test your code there. If you still get the same result you can check it on different computer, maybe with some other OS.
Sorry that I cannot give you any positive answer. I hope that melt/dcast code can give you desired result, though.
Cheers
