John Kane: I have 120 columns in a data.frame. I have one value in a column named "blaw" that I want to change. How do I find the coordinates?
Roger Koenker: It is the well-known wicked which problem: If you had (grammatically incorrectly) thought "... which I want to change" then you might have been led to type (in another window):
?which
and you would have seen the light. Maybe that() should be an alias for which()?

R-help (August 2006) #Rstats

You need to get the hang of reading the online help. The information required is actually there in ?dotchart --- it's just tersely and obscurely expressed. A certain degree of optimism is required. You need to ***believe*** that the information is there; then ask yourself "What could they possibly mean by what they have written that would tell me what I need to know?".
-- Rolf Turner (on reading the help pages)

The problem, as always, is what the heck does one mean by 'outlier' in these contexts. Seems to be like pornography -- "I know it when I see it."
-- Berton Gunter (quoting Justice Potter Stewart in a discussion about tests for outliers)
R-help (April 2005) #Rstats

Just now I had an apparently insurmountable problem that's been bugging me for days, but phrasing my question in a form suitable for the R-help list enabled me to solve my own problem in two minutes flat.
Thanks everyone.

Is this English or American (you know, the language referred to in the USA as 'English')? [...] As an English English speaker, my sense and my employer's dictionary both suggest doubling here.
-- Brian D. Ripley (in a discussion whether it is 'subsetable' or 'subsettable')
R-devel (February 2004) #Rstats

Dave Lubbers: R 2.7.2 - the manual says configure, make, which is what I did. So I did read the manual and followed the directions. The manual is too terse to get me there.
Duncan Murdoch: You used the wrong tense. In referring to R 2.7.2, only past tenses are grammatically correct. If you want to say "the manual *is* too terse", then you need to install R 2.11.0.
-- Dave Lubbers and Duncan Murdoch (on where to find libRmath)

memory problems (not me. my pc!)
-- Sara Mouro (subject line for an R-help request)
R-help (January 2008) #Rstats

Igor Sosa Mayor: The problem is that it gives the result that I want.
Sarah Goslee: That's a new sort of problem.

R-help (March 2012) #Rstats

As one of the developers of the nls function I would like to state that the lack of automatic ANOVA, R^2 and adj. R^2 from nls is a feature, not a bug :-)
-- Douglas Bates (in reply to a request for automatic ANOVA of NLS models as in Statistica)
R-help (August 2000) #Rstats

The existence of a method is not a sufficient reason to use that method.
-- Jari Oksanen (about relative advantages of several multivariate analysis methods)
R-SIG-Ecology (November 2013) #Rstats

Your example requires all choices of 1541 out of 3000, which I would expect to take somewhere near age-of-the-universe seconds to compute. The code uses a clever nested computation due to Gail et al which will cut that time down to infinity/10.
-- Terry Therneau (on an example with exact computations in coxph)
R-help (June 2016) #Rstats

I suggest that we redefine "+" to be a legal character in the name of an identifier. Sure, if you used to have "a+b" you'll have to rewrite it as "+(a,b)", but think of the benefits! You+can+write+out+long+sentences+and+use+them+as+variable+names!
-- Duncan Murdoch (in a discussion whether to use underscore, dot, or mixed case in variable names)
R-help (May 2005) #Rstats

Spencer Graves: What do you think about adding a "No RTFM" policy to the R mailing lists?
Michael Dewey: You raise an interesting point but the responses to your post remind us that people (and indeed whole cultures) are not all situated at the same point on the continuum of directness between "It's a cow, stupid" and "From this side it looks not unlike a cow".
-- Spencer Graves and Michael Dewey (reply after a long discussion of a potential "No RTFM" policy)

John Miller: How do I prevent google search to post my questions asked here??
Martin Maechler: you don't: R-help is famous and celebrity can't be gotten rid off ;-)

3-D bar plots are an abomination. Just because Excel can do them doesn't mean you should.

R-help (October 2007) #Rstats

I'll go back to lurking in the daily R-Helps and not ask any more questions until I've read all the old R-help messages. I'm working on December 1998 right now and reading forward. Perhaps by next year I'll will have read all the old R-help postings and I'll dare ask another question then.

Yes we CRAN!

private communication (July 2009) #Rstats

Note that there is a reasonable discussion in Writing R Extensions, but as always, you have to find it first.
-- Dirk Eddelbuettel (in a discussion about where to include data-generating scripts in an R package)
R-pkg-devel (March 2016) #Rstats

So apparently you wish to report as a bug the fact that R 1.8.0 is different from R 1.4.0.
-- Douglas Bates
R-devel (October 2003) #Rstats

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.
