I still don't know what to do about the compromise between how statistics should be done and how journal editors seem to insist it should be done ...

Etienne B. Racine: I haven't seen any documentation about this behavior.
Edzer Pebesma: Isn't the more important question whether you saw documentation that is in conflict with this behaviour?
Tom Gottfried: Taking that to the extremes: undocumented software always works perfectly.

R-SIG-Geo (February 2012) #Rstats

It is becoming apparent that you do not know how to use the results from either system. The progress of science would be safer if you get some advice from a person that knows what they are doing.
-- David Winsemius (in response to a user that obtained different linear regression results in R and SPSS and wanted to know which one to use)

It's not a question of trying variations, rather of following instructions.
-- Brian D. Ripley (about using 'Writing R Extensions')

As the name says, studentizing is left as an easy student exercise. Destudentizing is more difficult and usually called professorizing.
-- Dieter Menne (in response to a question whether residuals from nls() are studentized)
R-help (April 2009) #Rstats

There's an informal tradition that those announcements [about R releases] contain at least one mistake, but apparently I forgot this time, so users have to make up their own....
-- Peter Dalgaard (about an apparent non-bug report in his former R-announce message)

You are going to need a few more sessions for this therapy to be useful, we cannot read your computer's mind, just interpret what you tell us. I don't want to jump ahead, but can you tell us the childhood of your crashes, etc.
-- Romain Francois (in a 'psychotherapy' session trying to understand the sources of a useR's problems)
R-help (November 2009) #Rstats

I begin to think that R needs a _mis_fortunes package...
-- Stephen L.R. Ellison

Seldom are prizes, credit, and gratitude given, else Brian would be drowning in them.
-- Anthony Rossini (about the merits of implementing software)

Firstly, don't call your matrix 'matrix'. Would you call your dog 'dog'? Anyway, it might clash with the function 'matrix'.

Finally, as author of the code used to put CG in optim, I'll advise against its use. One of my least successful pieces of code. Rcgmin is better, but you really do need analytic derivatives to make it sing. For 5 parameters, use NM, or better the nmk from dfoptim package.
-- John C. Nash (in a discussion about optimization of a multinomial log-likelihood)

As Brian says, there's nothing in the design that lets you do this, but then since you have the source there's nothing on the planet to stop you doing this. The design is not a law :)

The keyboard is the standard Italian layout, which is missing the ~ (tilde) key. [...] Can anyone advice how to produce the ~ symbol, short of a copy/paste from MS Word?

Does anyone know someone working in this area in France who is not a JARP (Just Another R Person)?

I quit using SAS in 1991 because my productivity jumped at least 20% within one month of using S-Plus.

Duncan Murdoch: Others need to run under ESS.
Francois Pinard: While this is a good things for Emacs lovers, the requirement is rather unwelcome for pagans! :-)
-- Duncan Murdoch and Francois Pinard (on the availability of command completion)

I wish there was a better way for me to learn this stuff than constantly being wrong in public.
-- Hadley Wickham (in a discussion about efficient expansion of vectors and algorithmic complexity)
R-help (July 2012) #Rstats

I see three drivers of problems with R.
The first is that R is useful. [...]
The second driver of problems with R is that it is both a programming language and an interactive language. There is a tension there that is unavoidable. [...]
The third big driver of problems is that R is not software, it is a community.
-- Patrick Burns (Inferno-ish R)
CambR User Group Meeting, Cambridge (May 2012) #Rstats

Unfortunately, this is one of those situations where as far as I can tell all of the real statisticians are out there playing with large data sets where the small-sample corrections are not so important and leaving the rest of us to figure it out for ourselves...
-- Ben Bolker (about the 'correct' degrees-of-freedom correction in Wald statistics for GLMMs)

Also, that's what Martin Maechler told me and he wrote the code so I trust him on that. I figure that if you have to trust someone to be meticulous and precise then a German-speaking Swiss is a good choice.
