Codes to run the hierarchical clustering model to estimate number of groups and group-size. The code uses two dataset, the spatial location of the capture and the maximum number of individuals captured at the location.

I used the WeightedCluster (http://mephisto.unige.ch/weightedcluster/), factoextra (https://rpkgs.datanovia.com/factoextra/index.html) and Nbclust (https://cran.r-project.org/web/packages/NbClust/index.html) package in R for the analysis.

library(WeightedCluster) library(factoextra) library(NbClust) 

The dataset requird need to have the following format,

Latitude Longtitude Number of indiviudals photo-captured 20.27764 79.38614 4 20.29808 79.37403 3 20.252 79.38497 1 20.32906 79.29086 2 20.33533 79.34514 2 20.36006 79.31292 3 

Running clustering with the data

x<- cbind(Longitude, Latitude) dst <-dist(x) clstr <- hclust(dst, method = "complete", members = Number of individuals)
