[R] savehistory in OSX version

[Day, Roger S.]

Thanks, Rob,

I'm still unsure on the key question. 
Is there any way in R.app to save the commands run 
in the Console into a *.history or .Rhistory file,
by running a command on the Console,
whether savehistory() or some other function call?
(I'm trying to semi-automate a regular backup procedure while
in a very long interactive session at risk of hanging.)
Can you say more what you mean by "interoperate" here?

Roger

Roger,

The history features on Mac OS's R.app are handled by R.app and is a
(small) superset of R's facilties, e.g. it supports multi-line history
recalls.

A disadvantage of this approach is that it's not possible to use R's
history() and savehistory() nor make usage completely identical. The
actual history files do 'interoperate', although you will loose the
multiline feature.

A good list for Mac OS specific discussions is r-sig-mac at r-project.org.

Hope this helps,
Rob
