[R] question about scrolling up

[Jonathan Baron]

Is there a way to scroll up to see R's output (in Linux, in
particular) without using the scrollbar (i.e., without using the
mouse)?  I find that hard to control.

This has become relevant because I've just discovered an
(apparently) undocumented feature.  If you write a file of
commands, you can run the file by saying source("file.R"), for
example.  If you include statistical tests in the file, they
won't run.  But if you say, source("rile,R",echo=T), they _will_
run.  Thus, you can include all your data analysis in the same
file and use this option setting to decide whether you want to
see it.

Of course, it is possible to save all the output to a file, but
that is almost as bad as having to use the mouse.
