some hypotheses: 1) your genes should be entrez ids encoded as character; 2) the rat organism database is not installed in your system.
@Giovanni I am also using this package but I am getting different error :
Error in x[seq_len(n)] : object of type 'S4' is not subsettable
Any comment on it ?
Thanks
