HexaQerrs {SOMEnv}R Documentation

Relative quantization error distribution on the SOM map

Description

Plot a SOM map with relative quantization error plotted as grayscale according to quartiles

Usage

HexaQerrs(bmus, qerrs, Coord, Row, Col, color = "black")

Arguments

bmus

Vector with Best Matching Unit for each experimental sample

qerrs

Vector with quantization error for each experimental sample

Coord

Prototype coordinates for plotting the map

Row

Number of SOM map rows

Col

Number of SOM map columns

color

color filling of the hexagonsType a message

Details

The function evaluate the relative quantization error for each prototype dividing the sum of quantization errors for experimental samples represented by the single prototype by the number of hits of the same prototype, then plots a SOM map with filled hexagons according to the relative quantization error

Value

Plot a SOM map with filled hexagons according to the relative quantization error
