trellis.device in .First (PR#6812)
1) On the first point, please do read the NEWS file for R 1.9.0.
.Rprofile and .First have always been run before the default packages are
loaded in .First.sys, to allow them to be changed.
So this *is* a documented change in behaviour, not a bug. If I do
.First <- function() {library(lattice); trellis.device()}
This happens on all platforms. You need
.First <- function() {library(graphics); library(lattice); trellis.device()}
That is true of starting any graphics device in .Rprofile or .First.
2) The second point is a long known problem with ESS/Emacs on some
systems. There is a PR against it already (I saw a few days ago). Please
don't add irrelevant issues to a bug report on another issue.

This makes me think that the .First is being processed before some of the other initializations. I had been assuming it is the very last thing done before it gives me control. This introduces a new problem---both 1.9.0 and 1.8.1. I did --vanilla as you suggested, in a directory without an existing .RData /cygdrive/c/HOME/tmp$ Rterm --vanilla R : Copyright 2004, The R Foundation for Statistical Computing Version 1.9.0 (2004-04-12), ISBN 3-900051-00-3 R is free software and comes with ABSOLUTELY NO WARRANTY.

on the q() issue, I report it as a continuation of behavior that has been discussed
on this list. I don't remember when. It has been an issue for me for a long time.
I am currently on XP HOME, I see this also on NT4.
I normally type just q()
This time I tried q("no").
It still freezes. I have to enter C-G to unfreeze emacs and then use the Task Manager
to kill the Rterm process.
