Directional nearest neighbour distribution

Global/local directed nearest neighbour distance distribution, conical wedge defining direction set.

Usage

nn_directional_distance_distribution(
  x,
  r,
  direction,
  epsilon,
  type = "local",
  antipodal = TRUE
)

Arguments

x

point pattern

r

ranges to consider, increasing vector

direction

unit vector(s) of directions of cones

epsilon

Cone central half-angle

type

"global" or "local" (default).

antipodal

Use antipodal symmetry (=double cone)? Default: FALSE
