I heard that there is a way in R to represent the details of distance matrix graphically. more precisely, different sections of our distance matrix can be presented in different colors. low values be presented in light colors and high values in dark. is there really a way of doing it??

Hi elisa,
In the example for the function "color.scale.lines" (plotrix) you will
find one method of coloring something (lines in this case) depending
upon the distance from something else (the starting point). With
judicious modification, I think it might do what you want.
