"Data Analysis and Graphics Using R - An Introduction"
I've now processed this document through Acrobat software. The
navigation keys in Acrobat Reader should now handle it properly.
The other advantage is a dramatic reduction in size, to half

Using R for Data ... (was "Data Analysis and ...")
I have posted a new version of my document on R.
I have corrected a number of errors and moved much of the
detailed material on data structures to follow the chapter
on exploration of multivariate data. I have changed the name;
it is now:

Tutorial Introduction to R
I have placed my ~100 page document:
Data Analysis and Graphics Using R - An Introduction
at http://www.maths.anu.edu.au/~johnm/r-notes/r-notes.pdf
The best way to access and print it is with Adobe Acroread
Reader. I am making it available "for personal study and
classroom use".
It is a pdf version of a Word 95 file. A code that prints as ??,

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
substantially compacted. Any ideas what may be wrong?
I have also tried recreating the pdf file. I also tried
R CMD build --resave-data --compact-vignettes DAAG
The data files compact alright (but I get the 'significantly better compression'

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

Additions to the datasets package?
I have posted, at http://wwwmaths.anu.edu.au/~john/r/newsets/
image (.rda) files, and first stabs at .Rd files for various data on
deaths in London from 1629 to 1939. (There are of course gaps.)
The sources (Guy 1882 & Stocks 1942) are documented in the
.Rd files:

postscript(), used from a pre R-2.6.0 workspace
I find that if start R-2.6.0 in a workspace with no .RData file,
load one of my workspaces from R-2.5.1 or earlier into R-2.6.0,
and then before doing anything else type postscript(file="z.ps"),
I get::
> ls()

> load(url("http://www.maths.anu.edu.au/~johnm/r/test5.RData"))

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

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

R-devel Digest, Vol 100, Issue 28
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.)

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), ...){

Muliple partial matches with pmatch
I am using R0.64.1 under Windows 95.
The help for `pmatch' states that:
If `duplicates.ok' is false multiple matches will result
in the value of `nomatch' being returned, and if it is
true, the index of the first matching value will be
returned.
The help for pmatch gives the following examples:

Plot Character Sizes in rw-0.90.0
I have two supposedly identical installations, one under Windows 95,
and the other (at home) under Windows 98. The puzzle is that under
my Windows 98 installation, symbols plotted by default or with pch
come out huge, at about 2.2 times the height of the axis labels.
Setting cex=0.5 seems about what is needed to fix the heights.
On the Windows 95 installation, the symbols come out just a little
