You mean the graphics? (In text mode, just use the scrollback feature
of your console or xterm - Shift-PgUp in the latter case)

Try setting par(ask=TRUE) and rerun the examples.

There's a reason for not making example() do that itself, namely that
it would fire up a graph window even for text-only example sections.
