Hi,
I need some suggestion on how I could modify the color on some
rectangle that I have created using "image".
In other words, I have a 5x5 matrix, say, m.
m <- matrix(rnorm(25), nrow=5)
I create a grid of rectangles by:
image(m)
Now I want to change the color of rectangle (3,3) to blue.
I don't know how this could be done, and searching the web has given
me no hint.
Thanks for your help.
