Details

This is a panel function for desplot which fills cells with a background color and adds outlines around blocks of cells. It does not add the text labels, numbers, or colors. The rule for determining where to draw outlines is to compare the levels of the factor used for outlining. If bordering cells have different levels of the factor, then a border is drawn. 'NA' values are ignored (otherwise, too many lines would be drawn). The code works, but is probably overkill and has not been streamlined.
