Dear Enrico,

thank you for your suggestion. I have
(setq inferior-R-program-name "d:/rw442/bin/x64/rterm.exe") in my .emacs
. Now I tried your proposal, but did not note any difference.
In general I don't have problems with ess and R, it's just the command
"library(XLConnect)". That leads to an immediate quit of the R-session.

As mentioned, I can call library(XLConnect) in a batch execution, and
for now I do it that way, if I need XLConnect. In future I will probably
use openxlsx, which seemingly works for me.

best regards,

Heinz
