You should check the posting guide on 

http://www.r-project.org/posting-guide.html

The output of sessionInfo() is important.

The above code is helpful, because we see that the problem comes from a call
to grf,  but it does not show the error. Since your data set probably is
large, best construct a dummy data set, or better, use some standard data
set as it comes with grf to show the error.
