It would really help to have some sample data to see what is happening. The best way to supply data to the help group is to use dput(). Type >dput for some basic information on using it
Have a look at and/or http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example for some hints. For this last link it is a good idea to follow the " reproducible example " link for more concrete suggestions. By the way calling a data.frame "data" is not a good idea. Data is a predefined function in R . Type ?data to see what I mean.
