Actually computes \(L = \sqrt{K/\pi}\).
Kfn(pp, fs, k=100)
a list such as a pp object, including components x and y
x
y
full scale of the plot
number of regularly spaced distances in (0, fs)
fs
A list with components
vector of distances
vector of L-fn values
number of distances returned -- may be less than k if fs is too large
k
minimum distance between pair of points
maximum deviation from L(t) = t
relies on the domain D having been set by ppinit or ppregion.
