[R] Write.fwf works from Mac, throws different number of row error in Windows

[Duncan Murdoch]

You need to give us something reproducible or we won't likely be able to 
help you.  Put together a small example that illustrates the problem, 
and it will likely be fixed pretty quickly, or your error will be 
pointed out.  (You need to give us a way to construct outframe, we don't 
have it.)
