In popsom: An Efficient Implementation of Kohonen's Self-Organizing Maps (SOMs) with Starburst Visualizations

Description

Compute the (x,y)-positions of points on the map.

Usage

map.position(map,points)

Arguments

map	An object of type 'map'.
points	A data frame of points to be mapped.

Value

A data frame with (x,y)-positions. The data frame has two columns:

The x-position of the corresponding point in the 'points' data frame.

y-dim

The y-position of the corresponding point in the 'points' data frame.
