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

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

`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

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.
