hex_neighbour_dist: [!] Calculate distances between neighbour SOM cells

In GegznaV/kohonen.hexagons: Hexagon plots for Kohonen self organizing maps (SOM)

Description

[!] Calculate distances between neighbour SOM cells

Usage

hex_neighbour_dist(X, method = "euclidean", ...)

Arguments

X	object of class kohonen (from package kohonen).
method	the distance measure to be used. This must be one of "euclidean", "maximum", "manhattan", "canberra", "binary" or "minkowski". Any unambiguous substring can be given.
...	Further parameters to be passed to dist.

Value

Data frame with distances between neighbour cells. Data frame has these variables:
Cell_ID1, Cell_ID2 ID codes of neigbour cells. IThese variables are sorted so that condition Cell_ID1 > Cell_ID2 is always true.
Distance distance between indicated neighbours.
Other variables are coordinates between neigbourhood boundaries: bedinning, end and center points.
