I believe you will find this is already fixed in R-patched and R-devel as 
the logs say  (2005-10-07)

r35790 Fixed a typo in aqua R code

and it seems to be that line.

You seem to have an old version of the R.app, because the R 2.2.0  
release R GUI has a work-around for that problem. Please update your  
R.app either from the R release or the nightly builds page:
http://research.att.com/~urbanek/R/

As Brian was saying, the error was fixed in R immediately after the  
release - strangely enough no one reported the error during the alpha  
and beta cycle although both the GUI and R binaries were available  
for download :(.

Unfortunately, the phrase "strangely enough" could be replaced with
``as almost always''.

Maybe we (the R-foundation) should give serious thoughts to
offer prizes for valid bug reports during alpha and beta
testing.  These could include
- Reduced fee for 'useR' and 'DSC' conferences
- being listed as helpful person in R's 'THANKS' file
  {but that may not entice those who are already listed},
  or even in the NEWS of the new relase 
  or on the "Hall of fame of R beta testers"

In order to discourage an increased number of non-bug reports we
may have to also open a "hall of shame" though...

Martin's point is generally very valid, but in the case of the 2.2.0 
release remarkably few of the bugs found since release were new in 2.2.0.
One thing we have learnt is that none of the testers seem to look at HTML 
help (which accounts for 2 of the 4 2.2.0-only bugs I counted).

What we need most is persistent help in testing each release, especially 
on unusual platforms.  How do we `incentivize' that?

I suspect that in the particular case of OS X the problem was  
probably visibility - it was the first time ever that nightly OS X  
binaries were available during alpha/beta phase (afaict), but I'm not  
sure how many people knew about it. I think posted about it on R-SIG- 
Mac during some discussion, but maybe I should have announced it more  
specifically somewhere. I'm, not even sure whether there was a link  
from the main page on CRAN. I would think that OS X users are more  
likely to rely on binaries, so the above is more relevant than on  
other platforms.
The latter sounds good to me, although I'm not sure how many of our  
users are striving for fame ;).

Hi Martin,
On Fri, Nov 04, 2005 at 09:58:47AM +0100, Martin Maechler wrote:
I'll take up the invitation to brainstorm.

As a user of R for a number of years, I'd really like to perform some
useful service.  I use a relatively obscure platform (FreeBSD) and I
can compile code.  I'd like to think that I'm in the target market for
beta testing :).  But, I'm timid.  I do not feel, in general, that R
core welcomes bug reports.

I think that there are several things that could be tried to encourage
more, and more useful, bug reports.

1) Put the following text on the *front page* of the tracking system, so
   that it is seen before the reader clicks on "New Bug Report":

"Before submitting a bug report, please read Chapter `R Bugs' of `The
R FAQ'. It describes what a bug is and how to report a bug.

If you are not sure whether you have observed a bug or not, it is a
good idea to ask on the mailing list R-Help by sending an e-mail to
r-help at stat.math.ethz.ch rather than submitting a bug report."

(BTW is this true also for alpha/beta testing?)

2) Try to use the structure of the reporting page to prompt good
   reporting.  On the report page, summarize the key points of
   identifying and reporting a bug in a checklist format.  Maybe even
   insist that the boxes be checked before allowing submission.
   Include seperate text boxes for description and sample code, to
   suggest that sample code is valued.

3) On either or both pages (and in FAQ), explain that thoughtful bug
   reports are valued and appreciated.  Further, explain that bug
   reports that do not follow the protocol are less valuable, and take
   more time.

4) Add checkboxes to the report page for alpha/beta.  (I suggest this
   for the purposes of marketing, not organization.)

5) On the report page, include hyperlinks to archived bug reports that
   were good.  Do likewise with some artificial bug reports that are
   bad.

6) Add an intermediate, draft step for bug submission, to allow
   checking.  If possible, include as part of this step an automated
   pattern matching call that identifies similarly texted bug reports,
   provides links to the reports, and invites a last-minute cross-check.

7) Keep a list of people who report useful bugs in alpha/beta phase on
   the website.  Many academics could point to it as evidence of
   community service.
8) I'm sure that you're being ironic!  But I will take the point
   seriously, for what it's worth.  I think that humiliating
   submitters who haven't followed the protocol is deleterious.  It
   seems like almost every month we see someone get slapped on the
   wrist for not doing something the right way.  Of course, it's
   frustrating that people aren't following the posting guide.  But,
   why is that?  Where is the breakdown?  It might be interesting to
   try some follow-up (an exit interview!). If someone has failed to
   follow the protocol, perhaps we should try to find out why it was
   confusing, or if they just ignored it.

   The R-core is surrounded by, and serves, a community that comprises
   people who are not sufficiently good at what R-core does to be
   invited in to R-core. But, we're clearly interested in what R-core
   produces.  Please don't assume that bug submissions that do not
   follow the R protocol are the consequence of deliberate
   malfeasance.  

   To paraphrase Ian Fleming: Once is happenstance.  Twice is
   incompetence.  The third time, Mr. Bond, is enemy action. So, ...

9) Publicly thank bug reporters whether their reports are useful or
   not.  I just googled 'R-devel thank' and you figure prominently,
   Martin :).

Cheers

Why not just have the bug-reporter forward the report to
the maintainer? From user perspective, they would have a
single point to report bugs.

I'm not advocating increasing manual processing of bug
reports by R Core, rather that an alternative to the
problem [of package bug reports] may exist.

Thanks a lot, 
Andrew, for your input!

A general point about your suggestions:  You seem to assume that
bug reports are typically entered via the R-bugs web interface
(which is down at the moment and for a few more dozen hours probably},
rather than via  R's builtin  bug.report() function or the
simple e-mail to R-bugs at r-project.org  [[which will also not
properly work for the moment, as long as the bug repository is
suffering from a fiber cable cut in Kopenhagen]].

For some dinosaurs like me, having to fill a web page rather
than sending e-mail would be quite a loss of comfort, but
actually, it might not be a bad idea to require a unique
bug-entry interface -- actually we have been thinking of moving
to bugzilla -- if only Peter Dalgaard could find a smart enough
person (even to be paid) who'd port all the old bug reports into the
new format..

indeed!

I think that's a partly wrong feeling; understandibly nourished
by some of our reactions about some "bug reports" that stemmed
from user misconceptions.  As you've remarked below, I've
expressed gratitude more than once for helpful bug reports.

Yes, in principile.  The only thing to be changed would be

indeed I was, partly.  The point was just that if the bug
reporting will be something like a challenge with prizes, we had
to discourage too many entries {which would be made just to try
to win (a|the) prize}.

Martin, you're very welcome.
Yes, that was the premiss of my suggestions.  Perhaps to supplement
these ideas, bug.report() could be rewritten to prompt useful
information, much as prompt() does. And simple e-mail to
R-bugs at r-project.org could be filtered to only allow entries from R
core, and/or a list of registered beta testers.
I see that this would be useful.  What are the challenges? If funding
is available, then I wonder if any of the linked organizations might
be suitable?

http://www.bugzilla.org/support/consulting.html
Absolutely, and the effect is appreciated.  Sadly, the average user
struggles to distinguish between a helpful and an unhelpful bug report
before sending it.
Yes, I see that.  I really don't think that we need prizes; I really
do think that we need to create an environment that actively mitigates
against the kinds of error that you/we find so frustrating. A sort of
TQM strategy.

Cheers

Andrew

If you haven't already it might worthwhile looking in to fogbugz and trac.

Fogbugz (http://www.fogcreek.com/FogBugz/) is a commercial bug
tracking software package.  It is very professional and has been
designed to make tracking and submitting bugs as easy as possible
(sometimes you do get what you pay for).

Trac (http://www.edgewall.com/trac/) is more of an integrated software
development environment (open source) offering svn repository
browsing, a wiki and bug tracking.  It makes it very easy to link
between bug reports and the commits that fix them (although I know
fogbugz does this too, and I'm sure bugzilla does as well).
