You posted a very similar question on SO and have gotten specific  
advice about what was needed for resolution. You have so far not  
responded constructively to those suggestions. Please choose one venue  
for your questions and stick with it. Cross-posting is deprecated on  
Rhelp. The SO advice to post a data example that creates the error  
appears on point. Both of those points are outlined in the Rhelp  
Posting Guide. If you choose to continue on Rhelp then I suggest you  
delete the SO question.
