spatial clustering in R (simple example)

Question

I have this simple data.frame

 lat<-c(1,2,3,10,11,12,20,21,22,23)
 lon<-c(5,6,7,30,31,32,50,51,52,53)
 data=data.frame(lat,lon)

Answer 1

As you have a spatial data to cluster, so DBSCAN is best suited for you data. You can do this clustering using dbscan() function provided by fpc, a R package.

library(fpc)

lat<-c(1,2,3,10,11,12,20,21,22,23)
lon<-c(5,6,7,30,31,32,50,51,52,53)

DBSCAN <- dbscan(cbind(lat, lon), eps = 1.5, MinPts = 3)
plot(lon, lat, col = DBSCAN$cluster, pch = 20)
