Thanks, Robert. I've had considered R as a possible tool for this effort. I actually used it briefly for a data visualization course I took a few years ago, but there's still a lot more learning I would have to do to accomplish this. On the other hand, it seems every other path I've tried has a large learning curve too, so I should give R another look. Thanks, -pd -- Peter Davis www.techcurmudgeon.com
