SPATIAL QUESTION: HOW TO MAKE POLYGONS AROUND CLUSTERS OF POINTS AND EXTRACT AREAS AND COORDINATES OF THESE POLYGONS?
Imagine that I have a large number of points (given by coordinates x and y) that vary in density per space. For the purpose of demonstration it could be generated like this: s <- data.frame(x=runif(10000,0,900),y=runif(10000,0,900)); plot(s)
I want to create polygons around the points where point density is greater than a selected threshold (for example, by using krieging or equivalent
