Hi, I am using the EBImage package for image display and analysis and want to read the cursor (mouse) position on the image. The R-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 ? thanks Peter ---------------------------------------------------- Peter Hietz Institute of Botany University of Natural Resources and Applied Life Sciences Gregor Mendel-Str.33 1180 Vienna, Austria tel: +43-1-47654-3154 fax: +43-1-47654-3180 email: peter.hietz at boku.ac.at

It is actually on a TODO list to implement the coordinate tracker, it should be done soon.
