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)
