Hi, I am using the EBImage package for image display and analysis and want to read the cursor (mouse) position on the image. The function "locator()" would be ideal, but this appears to work only on plots, not images.
> a <- Image((0:(w^2))/w^2, c(w,w)) > if ( interactive() ) display(a) > locator(n = 10, type = "p") Error in locator(n = 10, type = "p") : plot.new has not been called yet Is there a similar function that works with dispalyed images ?
