Color Question about image function in graphics package
...I see a red color in my image generated by image function. I
don't know what is the value of z in that spot.
Example:
aaa <- matrix(rnorm(36),4,9)
image(aaa)
Can I paint the cells at which their values are higher than a certain value
in image()?
Or I have to use some other functions,
best
