I run R 2.5.1 on a Mac, and use JGR as the front-end. When I performed an update.packages(), I believe it unpdated a component of JGR. I then quit and tried to relaunch JGR. It wouldn't launch. Instead it opened a panel that says: "Cannot find iplot Java classes. Please make sure that the latest iplots R package is correctly installed." I would appreeciate hearing of strategies for solving the problem. _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102 Gilmer Hall McCormick Road Charlottesville, VA 22903 Office: B011 +1-434-982-4729 Lab: B019 +1-434-982-4751 Fax: +1-434-982-4766 WWW: http://www.people.virginia.edu/~mk9y/
