summary.glm() print problem(?) with cor = TRUE
Hi,
I've had a look the bug list and searched though the R documentation, email
lists etc. but didn't see anything on this:
when I do:
summary(species.glm1, correlation = TRUE)
I get a correlation matrix like this:
Correlation of Coefficients:

pH * 1
I(pH^2) * B 1
Ca . . 1
I(Ca^2) . . B

Building a windows binary of a package on Linux
Dear List,
Can I build a binary package (.zip) for Windows on my Linux machine from
my package sources? There is no C, C++, Fortran code involved, just
plain ol' R. I read through the article by Jun and Rossini, but (on
first reading) this seems more targeted at building a Windows version of
R and Windows package binaries that contain C, C++, Fortran code that
needs to be compiled.
Thanks,

as.character and a formula
Dear list,
given this formula:
> fmla <- formula(y1 ~ spp1 + spp2 + spp3 + spp5)
> fmla[[3]]
spp1 + spp2 + spp3 + spp5
is this the intended behaviour of as.character:
> as.character(fmla[[3]])
[1] "+" "spp1 + spp2 + spp3" "spp5"
? Where does the extra "+" come from?
> as.character(fmla)

smbd fails to start on Fedora Core 4
Hi,
Having reset-up a print server from installation disks today, I did
something stupid and blindly copied the contents of /etc/samba from the
previous installation into the new installation.
Now smbd refuses to start (nmbd starts OK). I am currently using a blank
smb.conf file and the smb.conf file from the old installation. testparm
doesn't report any errors in the smb.conf from the old

Sweave and abbreviating output from R
Dear List,
I'm using Sweave to produce a series of class handouts for a course I am
running. The students in previous years have commented about wanting
output within the handouts so they can see what to expect the output to
look like. So Sweave is a godsend for producing this type of handout -
with one exception: Is there a way to suppress some rows of printed
output so as to save space

StructTS and arima and missing values
Dear List,
I am thinking about ways in which I might analyse some stratigraphic
data. The nature of the data series I have generates a number of issues:
1) The data I have in mind come from a sediment core sequence taken from
the bottom of a lake. The sequence is sliced into a priori defined
slices, in this case 0.2cm per slice. in this way a sequence of 0.2cm
slices is produced for the

\dQuote{} in \code{} not processed
Just wondering if this is the expected behaviour.
I was wanting to produce quoted text within \code{}, without manually
entering the '"'. \dQuote{} seems advisable after reading the Writing R
Extensions manual, so I tried \code{\dQuote{mytext}} expecting it to
produce "mytext" in monospace font (with ' ' round it in the R help
files) but it appears that

RESOLVED: R GUI for Linux?
1) As long as the developer version of tcltk is installed, I now have no problem compiling R with tcltk support on Fedora Core 3. After extracting the gunzipped directory, I switch to the new directory and execute the following two commands:
./configure ----enable-R-shlib

Follow-Up: R on FC4
Dear List,
A few weeks ago a discussion took place regarding Fedora Core 4 and
compiling R on that platform using the new version 4 of gcc and its
gfortran compiler.
gcc was recently updated to 4.0.1 on FC4 (4.0.1-5 in Red Hat Land) so I
thought I'd give compiling R a go on my laptop which needed updating
anyway. I've had trouble using the optimisation flags I used to use
under FC3 with

make hanging during compile of r-patched/R-devel on Fedora Core 3
Hi,
On a new Dell laptop, with a fresh FC3 installation (with latest updates
applied) I am experiencing make hanging consistently after/during
building grDevices. This happens when using the configure flag
--with-lapack (I have the LAPACK rpm distributed with FC3 installed).
The last two lines of output are:

Packages that require other packages - How?

The help page for library/require contains the following paragraph in

The source code for a package that requires one or more other

beginning of the source, and of course before any code that uses

Sweave and multiple graphs
Dear list,
I am using Sweave to build a small report. I want to produce a series of
figures, each figure containing a number of plots and then have them
included in the Sweave file.
An example would be to :
postscript(file = "ANCbwplot%03d.eps", onefile = FALSE, other options...)
oldpar <- par(mfrow = c(2,2))
....
do lots of plots to produce a number of eps files
....
