Kfn {spatial} | R Documentation |
Actually computes L = sqrt(K/pi).
Kfn(pp, fs, k=100)
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 )
|
relies on the domain D having been set by ppinit
or ppregion
.
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 |
