R help - Jan 2013 - graphical distance matrix

Dear R-family,
I made a distance matrix of about 2000 stations. its extremely hard to visualize
the details of that matrix. 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??
thanks in advance
regards

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.
