euclidean.direction.f: Euclidean direction on a plane
Description
This function is ancillary to mat.dissim and gives the direction from point A to B on a plane.
Usage
euclidean.direction.f(modsite, fossite)
Arguments
modsite
Vector: containing the x and y Euclidean values for a point.
fossite
Vector: containing the x and y Euclidean values for another point.
Value
A numeric single value representing the direction between the two points.
Details
Provides the quadrat correct direction from fossite to modsite.
