You're overlooking something like line 800 of the documentation for xyplot. [...] It's probably in the R-FAQ as well, since my original feeling was that this behaviour was chosen in order to confuse people and see how many people read the FAQ... :)

Justin: Is there a function that just does whatever I'm thinking (aka whatever my homework question is...)?
Joshua Ulrich: That's the magic_pony function.

I thought RStudio was amazing, but RStudio with knitr is approximately `formatC(round(runif(1, 1e8, 1e9)), digits=10, big.mark=',')` times better than RStudio alone!

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

Obviously I have not tested on an Alphabc...tuvwxyz system but it should work there.

The existence of a method is not a sufficient reason to use that method.

Although there is almost never a "No" in R, the best short answer is: "No".
-- Uwe Ligges (in response to the question whether R has a concept of "const objects" as in C++ that avoid modification)

I would heed the warnings and diagnostics. They are there for a reason. The Ostrich algorithm does not help you.
-- Dirk Eddelbuettel (in reply to a questioner who said he had not run R CMD check because he suspected other problems would be found)
Stackoverflow (November 2013) #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)

Bad English is the language of science.

JSS mailing list (February 2005) #Rstats

Only with a very high signal to noise ratio (e.g., high true R^2) can torturing data lead to a confession to something other than what the analyst wants to hear.

Rickyfox: Dang it how could I have missed this? Thx for the answer, I feel incredibly stupid now.
Juba: Never underestimate the power of R to make you feel stupid.

So, with the item in the original query:

if (x<-3) do_something;

if they wrote it as

if (x<(-3)) do_something;

there would be no problem (and no doubt about what went with what). Of course in complicated expressions this could induce an episode of ocular lispopia, but apart from that it's safe!
-- Ted Harding (about potential confusion between assignment and comparisons with negative numbers)
R-devel (August 2010) #Rstats

(3 times...rrrrgh...) and why do you think the mailing list is called R-*packages* ???????????
Please do
for(i in 1:20) cat("It's a package!\n")
-- Martin Maechler (after a newly released *package* has been called *library* three times in its announcement on R-packages)

If you really want to assess uncertainty you need to take into account that the models are false and that several models may capture different aspects of the data and so be false in different ways.

R-help (July 2007) #Rstats

One of the beauties of S and R is the syntax closeness to mathematical notation. Many of us know that Lisp has beauties that S can never have, but that's really in different beauty-space.

R-devel (February 2009) #Rstats

R is a strange, deeply flawed language that nevertheless has an enthusiastic and rapidly growing user base. What about R accounts for its popularity in its niche? What can language designers learn from R's success?

You might also consider a more informative subject line. "Help needed" is true for all questions (not answers) on R-help. Just think, why is this list called R-***help***?
