Description

The package provides a function som.plot() for generating high-quality plots of hexagonal self-organising maps (SOMs), which have been created with Teuvo Kohonen's SOM_PAK software.

Package: somplot
Type: Package
Version: 1.6.1

LazyLoad: yes

Two files are necessary for plotting the result of a SOM_PAK run:

  • The output file of visual provides the mapping of input patterns to the codebook vectors.

  • The input file holds all patterns of the dataset with class information in the last column.

A visualisation with default parameters can be created by calling the function som.plot( visfile, datfile). The plot can be customised, by providing additional arguments for colouring, scaling, orientation or legend.
