Sweave and scan()
I am introducing the scan() function to my class. Consider the following
file (Scanexamp.Rnw )
\documentclass[12pt]{article}
\begin{document}
<<>>=
height = scan()
64 62 66 65 62
69 72 72 70
part = scan(what = character(0))
"Soprano" "Soprano" "Soprano"
"Alto" "Alto" "Tenor"
"Tenor" "Bass"

vector-factor operation
I found myself wanting to average a vector [vec] within each level of a
factor [Fac], returning a vector of the same length as vec. After a
while I realised that
lm1 <- lm(vec ~ Fac)
fitted(lm1)
did what I want.
But there must be another way to do this, and it would be good to be
able to apply other functions than mean() in this way.
Cheers, Murray

Quit asking me if I want to save the workspace!
How do you stop R from putting up a dialog box when you quit Rgui?
(I use Windows and I never save workspaces that way)

MASS data sets
I'm running R 1.2.2 under windows 98 on a Pentium 133 laptop.
I can't seem to retrieve the package MASS data sets:

Warning message:
Data set `wtloss' not found in: data(wtloss)
> data(abbey)
Warning message:

And yet all the .rda files for the MASS datasets are in

Interlacing two vectors
I want to interlace two vectors. This I can do:
> x <- 1:4
> z <- x+0.5
> as.vector(t(cbind(x,z)))
[1] 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5
but this seems rather inelegant. Any suggestions?

Converting Fortran or C++ etc to R
I'm going to try my hand at converting some Fortran programs to R. Does
anyone know of any good articles giving hints at such tasks? I will post
a selective summary of my gleanings.

A printing "macro"
I am exploring the result of clustering a large multivariate data set
into a number of groups, represented, say, by a factor G.
I wrote a function to see how categorical variables vary between groups:
> ddisp <- function(dvar) {
+ csqt <- chisq.test(G,dvar)
+ print(csqt$statistic)
+ print(csqt$observed)
+ print(round(csqt$expected))
+ round(csqt$residuals)

R-project [.com?] [.net?]
I got a shock a few days ago when I accidentally visited
www.r-project.com . I thought that the r-project site had been hacked
until I realised my mistake. There is also a site www.r-project.net.
Both of these sites appear to be Japanese. Does anyone know anything
about them? I suppose that it is not unusual for names close to those of
popular sites to be used. It is good that they use a

Plotting symbols
Has anyone got a cute way of compiling a table of the available plotting
symbols?
I've been repeatedly pasting in
cno <- cno + 1
cno
plot(x,y,pch=cno)
which is tedious, and besides I have to note down the symbols by hand.

Accessing just the value of an object but not the attributes
I have the feeling that this is a dumb question but oh well ...
When I have an object x with several attributes,
y <- x will make a copy of x with all the attributes included.
What if I just want y to get the value assigned but nothing
else (no class, names, dim or other attributes)?

Recommended Packages
Having just update to R 2.6.2 on my old Windows laptop I notice that the
number of packages is growing exponentially and my usual approach of
get-em-all may not be viable much longer. Has any thought been given to
dividing "contributed" binaries into a recommended set, perhaps a couple
of hundred, and the remained. That way one could install the recommended
ones routinely and add in

text editor for R
Hi,
What is the best text editor for programming in R? I am using JEdit as the
text editor, however, it does not have anything specific for R. It will be
nice to have a developing environment where the keywords are highlighted,
plus some other debugging functions.

Fitting models in a loop
If I want to display a few polynomial regression fits I can do something
like
for (i in 1:6) {
mod <- lm(y ~ poly(x,i))
print(summary(mod))
}
Suppose that I don't want to over-write the fitted model objects,
though. How do I create a list of blank fitted model objects for later
use in a loop?

Rgui front-end has encountered a problem and needs to close
Well I don't know if anyone can help with this but it will be
interesting to know if others have had the same problem.
I can't start R at home on my laptop [ I'm using 1.8.1 under Windows
XP]. When I click on the shortcut I get the usual Windows box for when
an application needs to close. A couple of clicks down it displays the
following:

I would like a function to strip quotes off character strings. I should
work like this:

> AF
First Second Third

Html help
I have just installed R 2.11.1 on my XP laptop.
I like html help for browsing but text help for on-the-fly look-ups. I
was a bit surprised when I was asked to choose between them during the
installation. I chose text, thinking I could fix the html help later,
which is what I am trying to do now.
Now when I ask for html help my browser goes to

likelihood and score interval estimates for glms
G'day list!
I'm thinking about programming likelihood and score intervals for
generalized linear models in R based on the paper "On the computation of
likelihood ratio and score test based confidence intervals in
generalized linear models" by Juha Alho (1992) (Statistics in Medicine,
11, 923-930).
Being lazy, I thought that I would ask if anyone else on the list has
