r |
Optional. Vector of values for the argument r at which K(r, s) should be evaluated. |
s |
Optional. Vector of values for the argument s at which K(r, s) should be evaluated. |
rmax |
Optional. Maximum desired value of the argument r. |
smax |
Optional. Maximum desired value of the argument s. |
nrval |
Optional. Number of values of r for which K(r, s) will be estimated. |
nsval |
Optional. Number of values of s for which K(r, s) will be estimated. |
intenssX |
Optional. Values of the estimated intensity function in 3d space.

If inhomogeneous it is assumed that the intensity of the space-sphere points is the product of the intensity in space and intensity on the sphere.
A list containing r
, s
, theo
, and K3dsph
.
theo
is the theoretical space-sphere K-function under Stationary Poisson.
theo
and K3dsph
are matrices with length(r)
rows and length(s)
columns.
