Unformatted text preview: normalized to a unit square (x and y coordinates between [0,1]), except if m is a Nx2 matrix and scaling=0. In that case too, the coordinates must be in range [0,1]. Following heuristic color codings are available: 'rgb1' slice of RGB-cube so that green - yellow the corners have colors: | | blue - magenta 'rgb2' slice of RGB-cube so that red - yellow the corners have colors: | | blue - cyan 'rgb3' slice of RGB-cube so that mixed_green - orange the corners have colors: | | light_blue - pink 'rgb4' has 'rgb1' on the diagonal + additional colors in corners (more resolution but visually strongly discontinuous) 'hsv' angle and radius from map centre are coded by hue and intensity (more resoluton but visually discontinuous) See also SOM_CPLANE, SOM_SHOW, SOM_CLUSTERCOLOR, SOM_KMEANSCOLOR, SOM_BMUCOLOR.
