[R] more outrageous plotting

[Juan Pablo Fededa]

Dear Contributors:

I have the next matrix:

"X" "Y" "Z"

1     2      526
2     5      723
3    10     110
4     7      1110
5     9       34
6     8      778
7     1       614
8     4       876
9     6       249
10   3       14

I want to order the matrix from bigest Z (1110) to lower Z (14).
Then I want to asign a color scale vector from blue ( bigest Z) to
orange (lower Z), and then I want to make a plot with the X vs.Y
coordinates of the matrix, with the number correspondent to Z in every
point, each number coloured with the assigned colour scale colour.
Is this doable?????
Thanks in advance again,



Juan Pablo
