K-function cross-type in 3D

Calculates an estimate of the cross-type K-function for a multitype point pattern.

K.cross.3D(
  X,
  Y,
  Z,
  X2,
  Y2,
  Z2,
  psz = 25,
  width = 1,
  intensity = NULL,
  intensity2 = NULL,
  parallel = FALSE,
  verbose = FALSE
)

Arguments

X

X coordinate of first observed point pattern in microns.

Y

Y coordinate

Z

Z coordinate

X2

X coordinate of second observed point pattern

Y2

Y coordinate

Z2

Z coordinate

psz

pointsize used for discretization. Smaller values are more precise, but need more computation time.

width

maximum distance

intensity

intensity of first pattern. Only if $$\lambda(s)!=\lambda$$.

intensity2

intensity of second pattern

parallel

Logical. Can we use parallel computing?

verbose

Plot verbose information

Value

a list of breaks and counts.
