Michael,

to understand you problem, I started creating a data set that simulates the
data, but I got stuck with with your intended meaning of "groups.

df =    data.frame(p=rnorm(100),count=rpois(100,5),dataset=c("A","B"),
  model=rep(c("M1","M2"),each=50),groups= dont' know)

Could you please (as the posting guide says) supply a self-running example that
shows the problem? 

You named your data.frame "data.frame"; it could work, but better don't use
common things like "c" or "data.frame" as variable name.
