Hello, I am a very new user of R, but have used S-Plus for about a year or so. I am curious about methods of creating simulated patch landscapes in R, and how to parameterize patch cover values and modify the periodicity/regularity of the patches in said landscapes. Can anyone point me in the right direction?
If you have access to GRASS GIS, check out: http://grass.itc.it/grass64/manuals/html64_user/r.surf.fractal.html not sure if there is an implementation in R.

Forgot to mention the RandomFields package. require(RandomFields) example(soil)

... or you could try the geostatistical indicator simulation formalism in gstat: require(gstat) demo(uisim) -- Edzer
