Compute K-fn of a Point Pattern
Usage
Kfn(pp, fs, k=100)
Arguments
pp
|
a list such as a pp object, including components x and y
|
fs
|
full scale of the plot
|
k
|
number of regularly spaced distances in (0, fs )
|
Description
relies on the domain D having been set by ppinit
or ppregion
.
Value
A list with components
x
|
vector of distances
|
y
|
vector of L-fn values
|
k
|
number of distances returned -- may be less than k if fs is too large
|
dmin
|
minimum distance between pair of points
|
lm
|
maximum deviation from L(t) = t
