[R] Suppressing (or changing) the colours when using spatstat plot.quadratcounts
Hi, Using the quadrats and quadratcount functions in spatstat, when I go to plot either of these, I get the quadrats coloured by their identity, i.e., using a color ramp applied to the sequence of quadrats. This only happens when the quadrats are applied to an owin which is polygonal, i.e., when I have an irregularly shaped study area. There doesn't seem to be any obvious way to over-ride this behaviour that I can find. I would ideally like to be able to colour the quadrats by the number of points/events each contains, rather than by their identity. Anyone run into this? It seems like an obvious request, maybe I just haven't spotted the necessary option, although I think maybe not - it's something to do with how plot.tess() works.
