[Rd] Request to Replace Recordplot ,, replayplot

no need to repost and start yet another thread on the same topic as
you posted yesterday (R-devel thread ''ReplayPlot, limited to single
session for RecordPlot()", 2014-04-30).  It just makes it hard to keep
a constructive conversation in one place and it clutters up the

Replaying plots within the current session is still useful. I'm sure
others would love to be able to replay saved R plots across sessions.
However, there was (most likely) a very good reason for not using it
across session, which is why R added the assertion that it's not done
- it's to avoid harm/misuse.

If you search the R-devel archives [http://www.rseek.org/], you'll
find some discussion on this topic, e.g. R-devel threads
"inconsistency/bug in recordPlot/replayPlot", 2014-09-23
You'll find that Paul Murrell and others have though about this a lot.

Hopefully, this gives you enough to research to appreciate the problem.
