Hi , The problem that I am facing is as follows : I have a .gif image (in grey scale) on my desktop . I want to read that image on R and make some changes to the greyscale values. I read the image with read.gif , but what command should I use to display the image in such a way that I am able to see the coordinates as I move the cursor over the image . Please suggest what to do . Thankyou Madhura. [[alternative HTML version deleted]]
