Hi, 

I am looking to perform a kernel density analysis in R, following the script that a friend of mine is using successfully. However, unlike for her, when I enter >kud<-kernelUD(data, h="LSCV"), R crashes and closes every time. This does not happen when I perform a different kernel analysis (>kud<-kernelUD(data))..

I have tried to un-install and re-install R, but it still crashes..


The script I am using is as follows: 

library(adehabitatHR)
library(maptools)
data<-read.csv("sa 4 trips 13F.csv")
xy = data[c("X", "Y")]
id<-data[,c("ID")]
coordinates(data) = c("X", "Y") 
class(data) 

kud<-kernelUD(data) # this works fine
kud<-kernelUD(data, h="LSCV") # this causes R to crash


Any suggestions would be greatly appreciated.

Many thanks for your time, 

Kind regards,
-Amanda-
