Thanks for the reply Virgilio, 2) Will opgam/kn.iscluster only detect hotspots or will they also detect coldspots i.e. areas of statistically unlikely lower incidence rates ? You get a p-value, so you could take the areas with very large p-values as cold-spots. But detection of cold-spots is

Hi all, I'm wondering if I can get a little advice on using DCluster. I have produced a map of areal incidence rates and I'd like to try and detect clusters. I have also implemented Bayesian smoothing and have therefore pre and post smoothing maps. I have some code as follow for detecting
