Dear list members
I am calculating kernel home-ranges and would like to visualize them with the function image(). The xy-values consist of longitude and latitude data.
example:
      x        y
36154.97 355143.0
 
R-code:
xy<-hares[,c("x","y")]
id<-hares[,"date"]
 
(ud1 <- kernelUD(xy, id))
ud2 <- getvolumeUD(ud1)
image(ud2)
 
My problem is that the image of the contours is cut at the edges. I tried to include the largest and smalest xy values with xlim and ylim. The contours shift on the Graphics Device of R, but the contours are still cut.
 
Can anybody help with this problem?
Thanky you very much!
Regards, Stéphanie Braun
