I have a file with 3 cols as:
x y value
1 1 0.5000
1 2 1.8333
1 3 4.3333
2 1 0.7500
2 2 0.7500
2 3 4
3 1 0.7500
3 2 1.4167
3 3 5.1667
I read them in using
p <- read.table("data.txt", header=TRUE)
My questoin: how to draw a image to show the values at different positions
(x, y)? I would like to see different colors for different values.
Sorry if it is a naive question, but it is my first week of R and I have
been trying for several hours trying to make it.
Thank you,
