Side be side legend items?
Am I right in thinking that legend() inevitably places the
successive items ine under the other, that it there is
at present no provision (short of multiple calls to
legend()) to place them side by side in multiple columns?

I am not sure how this should be handled. I encountered it
in connection with densityplot(). In that connection, it
might be enough to modify density() so that it

Use of Rd2txt on .Rd files from rw-1.0.0 (PR#498)

Subject: Use of Rd2txt on .Rd files from rw-1.0.0
Files generated using prompt.data.frame() under rw-1.0.0 get
scrambled (mildly) when I process them under Rd2txt on Solaris,
(using R-devel 1.1.0).
Files generated under R-devel 1.1 on Solaris are processed ok.
The .Rd files from the two sources look identical. The problem

Symbolic substitution of expressions into expressions
In the following
titletxt <- substitute(paste(tx, tilde(y) == sqrt(y)),
list(tx="Replace y by "))
I'd like to be able to replace e.g. sqrt(y) by a symbol or
symbolic expression that has the effect of inserting sqrt(y)
into the place that it occupies. This would allow me to put an
arbitrary expression into that position. [One can use text() or
mtext() etc. to place titletxt

Multiple expressions, when using substitute()
expression() accepts multiple expressions as arguments, thus:
plot(1:2, 1:2)
legend("topleft",
expression(y == a * x^b,
"where "* paste(y=="wood; ",
x=="dbh")))
Is there a way to do this when values are to be substituted
for a and b? i.e., the first element of the legend argument
to legend() becomes,

Compression of largish expression array files in the DAAGbio/inst/doc directory?
The inst/doc directory of the DAAG package has 6 files coral551.spot, ... that
are around 0.85 MB each. It would be useful to be able to zip then, but that
as matters stand interferes with the use of the Sweave file that uses them to
demonstrate input of expression array data that is in the "spot" format. They
do not automatically get unzipped when required. I have checked that

L-shaped boxes with lattice graphs?
Can anyone suggest an equivalent, for lattice graphs,
of the base graphics argument bty="l"?
NB that I am leaving off the box around the strip,
with a strip function:

factor.levels=as.expression(levlist), ...){

Use of R in Schools
I am looking for information on experimentation with the use
of R in the teaching of statistics and science in schools. Any
leads would be very welcome. I am certain that there is such
experimentation.
I've made this inquiry on r-sig-teaching, with no response.

I get the same style of path as Hadley. This is on Windows 7 Home Premium with SP1.
I start R by clicking on the R-2.31.0 icon.
I'd assumed that it was a change that came with R-2.13.0!
(On 32-bit Windows XP, which I have just checked, I do indeed get the 8.3 paths.)

Correction in help(factanal)
<<<
Thus factor analysis is in essence a model for the correlation matrix of x,

This should surely be ? = ??' + ?
Also line 3 under ?Details? says

x is here surely a column vector, albeit the transpose of a row vector

Bug report 14459 -- procedure for handling follow-up issues
Although the specific behaviour that was reported has been fixed, bugs
remain in Sweave's processing of comment lines when keep.source=TRUE
This is in some senses a follow-up from earlier bugs. Hence the query --
what is the preferred procedure, to submit a new bug report? (Another option
might be to add a comment to the web page for bug 14459.)
Is there now a preference to submit via

Enhanced version of plot.lm()
I propose the following enhancements and changes to plot.lm(),
the most important of which is the addition of a Residuals vs
Leverage plot.
(1) A residual versus leverage plot has been added, available
by specifying which = 5, and not included as one of the default
plots. Contours of Cook's distance are included, by default at
values of 0.5 and 1.0. The labeled points, if any, are those

Failure to get compactPDF to compact a pdf file
I am failing to get compactPDF to make any change to a pdf file
that, a/c to the message from the CRAN upload site, can be very

hist() ignores 'probability=T' (PR#944)
In the following, 'probability=T' is ignored,
i.e. the vertical axis is labelled in
frequencies.
However hist(islands, freq=F) achieves the desired effect.

> hist(islands, probability=T) # Vertical axis gives frequencies
