Subject: intensity map / plot
Dear R-list,
I would like to generate an intensity map based on a x * y matrix.
Each point in the matrix should get plotted at the coordinate: x = column / y = row with
a color-intensity (for example gray-value) based on the actual value of this point.
Is there a convenient package / function for this kind of plot?
example data:
x <- matrix(rnorm(100*100, 0, 2), 100, 100)
thanks!
