This figure is the plot of prototype of a Self Organizing Maps(SOM)
result.The numeric data is a M*N matrix, M rows and N
columns.color2D.matplot can transform the numeric matrix to a color matrix
,but i have to put them  in  hexagon cells to reveal their topological
structure( M  hexagon cells in a column,N  hexagon cells in a row).

It seems that i have to use the GRID package in R.
