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.

I know this seems like a very easy question (and maye it is) but I've been trying to simulate nested data and been unsucessful so far.. I want to simulate a varying number of species within a group; and then create an array to store the results of my for-loop. For example: groups<-3 species$groups<-as.integer(runif(groups,1,10)) #species per functional group ###create arrays to store results p<-array(NA,dim=c(species$groups)) So, far this is not working... Thanks!
