markcorr_anisotropic | R Documentation |
Estimate the anisotropic mark correlation function (2d and 3d), as defined in Stoyan 1991, f. 5.4. (without the additional 'a'-marks)
markcorr_anisotropic( x, marks = NULL, r, f = function(a, b) a * b, directions, bw, adjust = c(1, 1), correction = "translation", bootsize = 1e+05, divisor = "d", normaliser = NULL )
x |
pp, list with $x~coordinates $bbox~bounding box |
marks |
if x is not marked (x$marks is empty), use these marks |
r |
Evaluate at these lengths. |
f |
test function of the form function(m1, m2) ..., returning a vector of length(m1) |
directions |
Matrix of directions, in unit vectors, one direction per row. Default: along axes. |
bw |
Bandwidths of epanechnicov kernels. Vector of two values, one for ranges and one for angles. |
adjust |
If bw not given, use bw=adjust[1]*0.15/lambda^(1/dim) for range and bw=adjust[2]*0.15*pi for angle |
correction |
"none" or "translation". Translation only for rectangular box. |
bootsize |
bootstrap size for estimating the normaliser if not given. |
divisor |
either "d" or "r". Divide by dist(i,j) ("d") instead of r ("r")? |
normaliser |
normalising constant under independent marking. If NULL, estimated with bootstrap. |
Default bandwidth: bw=adjust*0.15/lambda^(1/dim) for range and bw=adjust*0.15*pi for angle.
