I would recommend using data.frame(var1, var2, ...) and not cbind.data.frame(var1, var2, ...). I consider it bad form to directly call a method of a generic function. Sometimes it leads to errors, as a method should be free to assume that its inputs are of the class it was declared to accept. In the particular case of cbind.data.frame, I think it just calls data.frame.
