Without any code and structure of your data you probably does not get much 
help. See the bottom of any email. 

PLEASE do read the posting guide 
http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.

Probably somehow your data are not as you expect. What 

str(yourdata) tells you? Is it in compliance with function you use? 

Regards
Petr
