Hi Dmitry,

Based on the error message you provided, it is difficult to understand 
what happened and to provide help on this.  Could you provide detail 
information such as 

(1) the codes you are running before you get this error
(2) the output of sessionInfo()

These kinds of information will be much helpful than the error messages 
only.  

HTH,
Ting-Yuan
