pcf_anisotropic | R Documentation |
Estimate the anisotropic pair correlation function (2d and 3d), as defined in f 1991, f. 5.2-5.3.
pcf_anisotropic( x, r, u, h, stoyan = 0.15, lambda, lambda_h, renormalise = TRUE, border = 1, divisor = "d", ... )
x |
pp, list with $x~coordinates $bbox~bounding box |
r |
radius vector at which to estimate |
u |
direction to be converted to angles. Use |
h |
half-widths of epanechnicov kernels, vector of two values, one for ranges and and one for angles. |
stoyan |
If h not given, use h=c( stoyan/lambda^(1/dim), stoyan*pi) (cf. |
lambda |
optional vector of intensity estimates at points |
lambda_h |
if lambda missing and lambda_h is given, use this bandwidth in a kernel estimate of lambda(x). Otherwise lambda is set to constant. |
renormalise |
Scale lambda to align with Campbell formula. |
border |
Use translation correction? Default=1, yes. Only for cuboidal windows. |
The antipode symmetry makes it necessary to compute only on one half of the circle/sphere.
