- xdim, ydim
- dimensions of the grid
- the topology of the grid.
- an object inheriting from class
- type, ...
- graphical parameters.
"somgrid" records the coordinates of the grid to be used for (batch or on-line) SOM: this has a plot method.
The plot method for class
"SOM" plots a
stars plot of the representative at each grid point.
somgrid, an object of class
"somgrid", a list with components
- a two-column matrix giving locations for the grid points.
- xdim, ydim, topo
