Firefox is always already open, and sometimes the old test results are
already open too. Sometimes it takes minutes to open up, sometimes using
submit+step in emacs seems to be correlated with this getting this to go a

You should probably report ESS problems to their mailing list. I don't
use it or support it, and I don't know if they'll read this message
since it doesn't mention ESS in the subject line.

I just installed 2.10 on XP; ESS is my primary interface.
I seem to be able to access all the help files; under 2.8.1 I was having
seemingly random problems accessing some help topics (including one day
I could and a few days later I couldn't, and vice-versa). That's good.
I noticed a few glitches.
First, the installer asks if you want text, CHM, or HTML help, but
offers only text or HTML. I understand CHM has been removed; I guess
this is just an old message.
Yes, already fixed in the patched version.
Second, install.packages("intervals") produced the usual line about
selecting a mirror, but no selection list popped up. It just sat there
until I interrupted the session and reentered the command with a
pre-specified repos. I selected custom install but took the defaults; I
noticed there was some optional tk/tcl stuff (which I did not select);
I'm guessing it's required for these selections. Perhaps it should be
installed by default?
That's something I haven't seen before. I do get the mirror dialog, and
it doesn't use tcl/tk, so I'd appreciate hearing if you can spot any pattern
here (including the pattern "I never get it"). (The install option is about
installing the tcl/tk help files: mainly useful if you're developing with
tcl/tk, not necessary for most users. The Tcl/tk code itself is always
installed.) It could be that R is being blocked by your anti-virus
software; what it's trying to do is to read a list of mirrors from
This is a longstanding problem for R under ess/emacs on Windows (and maybe
Xemacs as well, but I don't know for sure).
Okay, I'll leave it to those guys to debug. If R is doing something it
shouldn't, let me know what, and I'll try to fix it. (I'd guess the problem
is that Emacs makes assumptions about the OS that just aren't true in
Windows, but it might be a bug we could work around.)

This problem manifests itself in install.packages(), but the real problem
comes from the line
if (.Platform$OS.type == "windows" | .Platform$GUI == "AQUA")
return(.Internal(select.list(list, preselect, multiple,
title)))
in select.list(). If you run R under ess/emacs and do something as simple
as
select.list(letters)
it will freeze and you have to use C-g, C-c C-c to 'unfreeze'.
Paradoxically, after doing so, select.list() will then function correctly.
You can get around this problem by first loading the tcltk package, if
that is of any help.
This problem only occurs under emacs/ess; if you run R from a DOS prompt
or via the GUI then select.list() works correctly the first time.
Best,
Jim
http://cran.r-project.org/CRAN_mirrors.csv
using the code in getCRANmirrors(). If that download fails or is delayed
forever, you won't get the selection list.
Third, every time one asks for help on a new topic there is a
considerable delay (seemed like forever, probably c 15 seconds) before
the help comes up. My first thought was that the on-demand help was
being assembled, but I didn't see much CPU use. It might be latency in
talking to MSIE, and this latency might even be from my (Sophos)
antivirus software, which kept warning me about a program suspiciously
launching MSIE. If you ask for help you already requested there is no
delay (good) and it does not focus on the tab with the relevant help
(which strikes me as the ideal behavior, though it may be hard to do).
When you ask for help the first time, it starts the internal server, but
that should be fast. Then it passes the URL to Windows to open, and Windows
needs to open the browser to show it, which tends to be slow. When you ask
subsequently, it will send the request to Windows again, but if the browser
is open, that should be quick. I'd guess this is your antivirus checking
out the URL; when I do it (with no antivirus checking on such things) it's
pretty slow on the first occurence (because it needs to start Firefox), then
pretty fast after that.
Fourth, I read the previous comments about how more beta testers would
be useful :)
Yep.
