somplot: Visualisation of hexagonal Kohonen maps

Download and install the R-package

The R-package somplot can be obtained directly from CRAN (The Comprehensive R Archive Network) by using the install.packages() function of R. Download and install the package “somplot” in one step with the following commands in the R console:

> install.packages("somplot", dependencies = TRUE)
> library(somplot)
>
> som.plot(system.file("test.data/iris4som.out", package="somplot"),
+ system.file("test.data/iris4som.dat", package="somplot"))

The example displayed above will create a visualisation from example data included in the package.

Usage

The function som.plot() has the two mandatory aruments visfile and datfile. visfile denotes the raw output of the SOM_PAK program visual and datfile denotes the original data file used as input for the SOM_PAK program vsom.

> som.plot(visfile="my-data.vis", datfile="my-data.dat")

More arguments for controlling properties of the visualisation can be found in the R-help by typing help(somplot).
