Subject: Simulate nested data

Hi Andrea,
Without knowing what species is, I can't run your code as is, but try this:
groups<-3
speciesgroups <- as.integer(runif(groups,1,10))
# I'd use sample(1:10, groups, replace=TRUE)
p<-array(NA,dim=speciesgroups)
Mostly you're trying to use c() on something that's already a vector.
