[R] Plotting device does not show all graphs

[Sarah Goslee]

Well, when I try to run your sample code, I get one figure and a bunch
of error messages.

How about an actual executable example and the requested basic
information on your OS, version of R, etc? That would make it a lot
easier to offer useful suggestions (by which I mean possible).

I get a boxplot only.

Can you actually run this code without error messages? Even if you
have loaded whatever library the missing plot functions came from,
hist(age) is not going to create a plot, thus you would only ever get
three files.
