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'

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

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

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.)

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.)

Why software fails in scientific research
I came across this notice of an upcoming webinar. The issues identified in the
first paragraph below seem to me exactly those that the R project is designed
to address. The claim that "most research software is barely fit for purpose
compared to equivalent systems in the commercial world" seems to me not
quite accurate! Comments!

Garbled plot label
Hello,
While using the "plot" function against a model with a long formula,
I get a garbled label in the bottom of the plot. It looks like there are
two lines printed one over another, here's my example:

Discrepancy between R and SPSS in 2-way, repeated measures ANOVA
Dear R community,
I am trying to resolve a discrepancy between the way SPSS and R handle
2-way, repeated measures ANOVA.

treatment of four groups of subjects (control and disease states 1, 2 and

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.

classification for huge datasets: SVM yields memory troubles
Hi
I have a matrix with 30 observations and roughly 30000 variables, each
obs belongs to one of two groups. With svm and slda I get into memory
troubles ('cannot allocate vector of size' roughly 2G). PCA LDA runs
fine. Are there any way to use the memory issue withe SVM's? Or can you
recommend any other classification method for such huge datasets?
P.S. I run suse 9.1 on a 2G RAM

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

Odd diagnostic plots in mixed-effects models
Dear R community,
In the excellent nlme package the default diagnostic plot graphs the innermost residuals against innermost fitted values. I recently fit a mixed-effects model in which there was a very clear positive linear trend in this plot.
I inferred that this trend occurred because my fixed effect was a two-level factor, and my random effect was a 12-level factor. The negative residuals
