+ 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.

using rect for this.

DUH.
