[R-sig-Geo] Variable point size with spplot

Dear list, I used to plot points of variable size with spplot this way: library(RColorBrewer) data(meuse) coordinates(meuse) - ~x+y spplot(meuse, zcol=om, col.regions=colorRampPalette(brewer.pal(7, PuBu)[-(1:1)])(20), scales=list(draw=TRUE), cex=.4*(1:5) ) but now,

[R-sig-Geo] great circle distances

Hi I need to calculate the average nearest neighbor distance between nests coordinates (lat/long). However, I would like to use the great circle distances in spite or Euclidian distances. Is it possible to do this in ArcGis 10? Thank you for your attention, Ana -- PhD student

Re: [R-sig-Geo] Creating a spatial boundary using Lines() and SpatialLines()

Dear Roger, Thank you for this helpful comment. The spatial boundary now works. However, when I submit it to KernelUD() using kernelUD(Movement_Spatial,h=href,grid=Raster_map,boundary=coastline) I get an error message Error in 3 * h : non-numeric argument to binary operator The boundary is
