UmatGraph {SOMEnv}

U-matrix plot

Description

Plot of Unified Distance Matrix using a colored scale according to quartiles

Usage

UmatGraph(umat, Row, Col, colorscale = c("bw", "gs"))

Arguments

umat

Unified Distance Matrix

Row

Number of SOM map rows

Col

Number of SOM map columns

colorscale

Either "bw" for grayscale or "gs" for green-white scale

Details

The function plots a U-matrix map for the values of each modeled variable using a grayscale according to quartiles, from darker color (lower distances) to lighter color (higher distances). The quartiles are evaluated by boxplot function applying default parameters.

Value

Plot of Unified Distance Matrix using a grayscale or (green-white scale) according to quartiles
