Simulate minefields with two samples in the same plot in R -


i trying simulate minefield plotting 2 poisson distributed samples in same plot, 1 higher intensity , smaller area other. minefield , other noise (stones, holes, metal) seen points. cannot r plot points same units in axis. whatever do, points span entire plot, though want x points cover quarter of plot. r-code following:

library(spatstat) y = rpoispp(c(5),win=owin(c(0,10),c(0,10))) x = rpoispp(c(10),win=owin(c(0,5),c(0,5)))

please let me know if can me.

my guess doing like:

> plot(y) > plot(x)

to plot points.

the problem default behavior of plot function class ppp (which rpoispp function returns) create new plot points. second plot call erases first plot, , plots own points in differently scaled window. can override behavior setting option add=true second plot. code

> plot(y) > plot(x, add=true, cols="red")

should like: plot of 2 poisson point patterns

check out docs (help(plot.ppp)) more explanation , other options prettify plot.
