[ESS] save commands to .Rhistory?

[Marianne Promberger]

Dear list,

In an R process buffer in Emacs/ESS, I can cycle through the history
of previous commands with C-uparrow.

But the history only contains commands entered directly in the R
process buffer. Commands sent from a command file to the process eg
via C-c C-c do not get added to the history.

The same pattern holds for which commands are, or are not, in the
local .Rhistory file after q().

I would like commands sent from an external command file to show up in
the history, too.

Possible?

Thanks,

Marianne
