Re: [R] Is there a function in R can help me to plot such a figure?

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.
