+  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.
