Hi, Thanks. I see that quadrats, Divides window into rectangular quadrats
and returns the quadrats as a tessellation. Do you know what they mean by
window? And I saw this:

W <- square(10)
 Z <- quadrats(W, 4, 5)
 plot <http://inside-r.org/r-doc/graphics/plot>(Z)

 data <http://inside-r.org/r-doc/utils/data>(letterR)
 plot <http://inside-r.org/r-doc/graphics/plot>(quadrats(letterR, 5, 7))


but my environment does not know what square() is.
