Dear listers, On a simulation purpose, I would like to generate data variying from random to various degrees of overdispersion on a raster grid.? For instance on a matrix 1000 x 1000, to select a number of pixels that could be considered spatially aggregated (with a possibility for tuning the degree of aggregation from "random" - no aggregation - to strong clusters). Has anyone heard about how to proceed or an idea about it?
This sounds very much like spatstat, but could you provide a short code example to show what the discretised output should be? Are these presence/absence in the grid cells? Best wishes, Roger
