[R] Redirect/pipe output to less

[(Ted Harding)]

Another approach may be useful. Back in May 2003 I raised a
similar query: How to divert R output into a separate X window
(in Linux) where it would apear after being piped through 'less'.
This has the advantage that, if you choose to do it this way,
it leaves your R console untouched. I raised the query in:

  https://stat.ethz.ch/pipermail/r-help/2003-May/034147.html

(start of thread) and, after a fairly lengthy exchange, I
summarised my initial implementation in:

  https://stat.ethz.ch/pipermail/r-help/2003-May/034230.html

with further refinements in:

  https://stat.ethz.ch/pipermail/r-help/2003-May/034233.html

See also the final comment by Greg Snow in:

  https://stat.ethz.ch/pipermail/r-help/2003-May/034238.html

This will cause all invocations of help() or '?', and of
help.search() or ??, to be displayed in a separate window
using 'less'. To display a large R object, say V, similarly,
use page(V), which will open a new window with X displayed
in it.

You can also do things like 'page(lm(Y ~ X1 + X2))'.

However, all that was a long time ago. Check 'page' in your
newer R!

Ted.
