Kest_gaussian | R Documentation |
Estimate K function -type summary for second order reweighted ("inhomogeneous") pattern using a Gaussian kernel sitting in the origin of the Fry-plot.
Kest_gaussian( x, u, kappa, r, lambda = NULL, lambda_h, renormalise = TRUE, border = 1, ... )
x |
pp, list with $x~coordinates $bbox~bounding box |
u |
unit vector(s) of direction, as row vectors. Default: x and y axes, viz. c(1,0) and c(0,1). This gives the major axis of the ellipsoid (direction of largest variance in the Gaussian density). |
kappa |
The ratio of the secondary axis to the main axis going along 'u'. |
r |
radius vector at which to evaluate. Corresponds to the radii of the 95% quantile in x-axis, before rotation in directions u. |
lambda |
optional vector of intensity estimates at points |
lambda_h |
if lambda missing, use this bandwidth in a kernel estimate of lambda(x) |
renormalise |
See details. |
border |
Use border correction? Default=1, yes. At the moment no other version available! |
... |
passed on to e.g. intensity_at_points |
TODO Gaussian kernel sitting at the fry-space, sum over fry-points.
Returns a dataframe.
