Kest (spatstat) and "r" values

Maybe the information related to r you are looking for is in the Warning section: "Warnings The estimator of K(r) is approximately unbiased for each fixed r. Bias increases with r and depends on the window geometry. For a rectangular window it is prudent to restrict the r values to a maximum of 1/4 of the smaller side length of the rectangle". Maybe I'm wrong but I think that Kest computest K(r) by default for r up to 1/4 of the shorter side of the *enclosing rectangle* of your window.
That is indeed correct, modulo a possible adjustment (which I believe rarely gets applied in practice) in terms of the estimated intensity of the process. See the code for rmax.rule() if you are interested in the details. cheers, Rolf
