regions in Gabriel graph
Dear list,
following the vignette of the package 'spacemmakeR' I have built a
gabriel graph of ten randomly placed points:
library(spdep)
set.seed(3)
xyir<-matrix(runif(20),10,2)
nbgab<-graph2nb(gabrielneigh(xyir), sym=TRUE)
plot(nbgab,xyir,points=FALSE)
points(xyir,pch=20,cex=2,col=c(2,4,4,4,2,2,4,2,4,4))
title(main="Gabriel Graph")
Now, I need to determine for any additional point whether it is
located within the region surrounded...
