They cannot. In order to get any help, it is essential that you paste a 
copy of your code into your message - including the error message(s), 
followed by the output of traceback() and sessionInfo() in that order. 
We don't even know which function in which package you are using, and 
whether you are using it correctly. As far as I know, no-one on the list 
can see over your shoulder ...
