Hello.
I've started recently using the adehabitat package with R 2.8.1 and i've been facing a strange error.
My main goal is to calculate kernelUD from shapefiles and send the results as a surface/shapefile so using this shapefile with random points here (
http://www.yousendit.com/transfer.php?action=batch_download&batch_id=UmNMMWZPK3gwMEd4dnc9PQ) i've been trying to run this code and i get an error on the last line.
The code is:
## load lbs
library(adehabitat)
library(shapefiles)
## load shapefile
shpobj <- read.shp("C:/Temp/2008.shp")
## convert it to simple X,Y
cds <- convert.to.simple(shpobj)
## get assure the XY coordinates are in here
xy <- cds[,1:2]
## run kernelud
hr<-kernelUD(xy, h="LSCV", grid=100)
------------> "Error in df[, 1] : incorrect number of dimensions" <------------
Any help on this would be appreciated.
Regards.
