Hi all;
Just to ask if you know about any available function in R to identify points
in a image plotted in X11. Something like the function identify(), but able
to extract (x,y,value) groups from the image.
Maybe, something like that?
z <- matrix(runif(100),10,10)
image(list(x = 0:9, y = 0:9, z = z))
p <- locator(1)
z[round(p$x), round(p$y)]
