But frame 2 of the Plot Package lab already loads plot. Indeed, were plot not already loaded, then you would see no plots whatsoever. But plots DO begin to appear already in frame 6. It's only later, in the frame I indicated, where the trouble starts.
P.S. Once again, Thunderbird under Windows truncated the entire message from [email protected] to just the first one. This does NOT happen with sequences of messages sent from other originators.

I believe the lesson said if you get an error message, then `load 'plot'`. Could you try that, please. Your comment that jhs has to be shut down and restarted is a little bit of a surprise. If that can be confirmed, I will try to add a warning in the video. -- Murray Eisenberg [email protected] Mathematics & Statistics Dept.
