Dear R-users, I'm trying to do some spatial simulation. I have two covariates, Z and C. I want to examine their relationship under different spatial distribution.
I have no problem simulating completely spatial random process but I'm totally stuck on poisson (cluster) pattern. I already have a dataset with Z and C (obs=575) and I know the relationship between them. Using these 575 cases, how can I simulate a clustered process and have a dataset that has four columns: x-coor y-coor z c I know I can use rpois or pcp.sim to generate points that clustered and then use cbind to attach Z and C values. But the problem is my observations will not be spatially clustered. How can I simulate so that now Z is spatially clustered? Thanks!
