I'm wondering if anyone is aware of a way to take what is visible in the R graphics window, pixelate it, and express that pixellation in a numeric matrix. For example, I am using the following command to create a black (present) and white (absent) spatial simulation of grass tussock distribution.
> symbols(x=runif(100,-.5,1.5),y=runif(100,-.5,1.5),circles=runif(100)/30, inches=F,bg=1,xlim=c(0,1),ylim=c(0,1)) What I would like to end up with is a 2 dimensional matrix that indicates presence/absence of grass in any given pixel as per the image generated from the above graphics plot.
