Plot a SOM map with realtive quantization error plotted as grayscale according to quartiles
1 | HexaQerrsQuant(bmus, qerrs, Coord, Row, Col)
|
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 |
The function evaluate the relative quantization error for each prototype dividing the sum of quantization errors for experimental sample represented by the single prototype by the number of hits of the same prototype, then plots a SOM map with the realtive quantization error represented as grayscale according to quartiles, from white (lower outliers) followed by grayscale (quartiles) and black (upper outiliers). The outilers and quartiles are evaluated by boxplot function applying default parameters.
