It seems you don't quite understand how foreach works. foreach (..) %dopar% { ... } takes the last value from each of the second {...} evaluations and feeds them to the .combine function (in your case rbind()). Since your last call in the %dopar% {...} block is assign(), you are not getting anything meaningful.
Make the last value a vector that you want to be "rbind-ed" to the result.
