I would like a great help from you. I used the cluster.stats function that
is part of the `fpc` package to compare the similarity of two custer
solutions using a variety of validation criteria, as you can see in the
code. However, I have two questions:
1 ° Is it possible to know which is the most viable cluster, 2 clusters or
5 clusters? If so, could you explain me better how I can know.
2º Does this package only compare two in two cluster solutions, or is it
possible to compare two more cluster solutions at once?
Thank you so much!
Best Regards.

d<-as.dist(distm(coordinates[,2:1]))
fit.average<-hclust(d,method="average")
clusters<-cutree(fit.average, k=2)
df$cluster <- clusters
clusters1<-cutree(fit.average, k=5)
df1$cluster <- clusters1
cluster.stats(d,df$cluster,df1$cluster)
