Can't get Sweave syntax highlighting with Emacs
I can't get Emacs to automatically do syntax highlighting of
Sweave files. I have followed Friedrich's suggestion for code
to insert into my .emacs file. The complete section from my .emacs
file is given below. When I load a *.Snw file, font is white until I press
M-x, then the first code and document chunks get highlighted, but not
the rest of the file. Latex and Noweb menus are

rimage doesn't install on Mac OS X 10.4
Hi,
I'm trying to install rimage on a Mac OS X 10.4 machine. I followed the
advice in previous R-help threads and got over the hurdles of having the
header files in the right places, among other things. But I can't
figure out what to do with this error.

Problem with R-2.1.0: install.packages() doesn't work
I installed R-2.1.0 from source on a Linux box running Red Hat
Enterprise Linux WS release 4 but install.packages() wouldn't work (see
below). When I install R-2.0.1 from RPM on the same system, everything
is fine.

Using an image background with graphics
I would like to use a map or aerial photo as a background to plotting
solid lines and text, and semi-transparent color contours, in base and
lattice graphics. Plot coordinates need to be consistent with the
georeferenced background. For example, a color contour plot would have
an gray-toned aerial photograph as a background for overprinted
semi-transparent color contours of some spatially

Possible to get a definition of a function from a package to use without invoking the package?
Hi,
I often use the mod() and instring() functions that are available in the
clim.pact package. This package has a lot of dependencies, including
installation of netCDF, and I haven't yet been able to get
library(clim.pact) to work on a Mac OS 10.4.6. A previous request for
help with the Mac problem yielded no results, so now I wonder if I could
just extract the definitions for the couple

Problem with number characters
I am trying to process text fields scanned in from a csv file that is
output from the Windows database program FileMakerPro. The characters
onscreen look like regular text, but R does not like their underlying binary form.
For example, one of text fields contains a name and a number, but
R recognizes the number as something other than what it appears
to be in plain text. The character string

levelplot and unequal cell sizes
I am using levelplot() from lattice with grids that have unequal cell
sizes. This means that the boundary between two cells is not always
half-way between nodes, as levelplot() assumes. The result is that some
cell sizes are rendered incorrectly, which can be painfully obvious if
using relatively large cells. Is there any work-around? I am using the
conditioning capability of lattice and

Using contour3d: axes, plotting to file, with lattice
I am looking for examples of how to plot with contour3d() to a PNG or PDF file, add axes and other elements to the isosurface plot, and use contour3d in conjunction with lattice. Regarding lattice, I'm not necessarily looking for conditioning on the data shown in the isosurface plots, just a way to show multiple plots in one figure and label them. I am new to the packages misc3d and rgl.

Vertical bars with barchart()
I would like to create a barchart that has vertical instead of horizontal
bars. My goal is something similar to Figure 6.10 (p. 166) in
"The Basics of S and S-plus," except for the orientation of the bars.
I don't think bwplot() or xyplot() will work. Any suggestions?

change lattice panel background color
I can't find a way to change just the panel background color in lattice.
I would like NA regions in levelplot() to appear black. I've tried the
trellis.par.set() stuff, but it it makes the background of the whole
graphic black.
Thanks,

dev.off() prematurely stops xyplot()
I have a script containing an xyplot() to print to a postscript
file, followed by dev.off(). When I source the script, the dev.off()
seems to cut off the xyplot() execution before it is finished.
The resulting postscript file has about the right size, but it
appears blank when I try to view it. If I manually execute the
xyplot(), then wait for the return of the R prompt before executing

Example scripts for trellis graphs
How can I access examples of trellis graphs in R? I'm especially
interested in getting code for xyplot() examples.
Failing a collection of examples in R, I see that
under Splus there are numerous example.*() functions. I can
access Splus with a command line but can't open a graphics window,
so I can't to execute the example.*() functions. Is there a way

Parallel computing with the snow package: external file I/O possible?
Hello,
After getting help to solve part of my problem and some delay on my
part, I am posting a more refined version to see if someone can help me
further. I am trying to autocalibrate a model in my subject area using
the snow and rgenoud packages. I want to use the key function "fn" that
is called by genoud() to finalize input, run the model executable, and
compute the objective

Screen settings for point of view in lattice and misc3d
I'm making some 3D plots with contour3d from misc3d and wireframe from lattice. I want to view them from below; i.e. the negative z-axis. I can't figure out how to do so. I would like my point of view looking up from below, with the z, y, and x axes positive going away. Can anyone tell me the correct settings for screen to achieve this? Here is what I've found so far:

Trying to understand kpss.test() in tseries package
I'm trying to understand how to use kpss.test() properly. If I have a
level stationary series like rnorm() in the help page, shouldn't I get a
small p-value with the null hypothesis set to "Trend"? The (condensed)
output from kpss.test() for the two possible null hypotheses is given
below. I don't see any significant difference between these results.

Timeliness of precompiled binaries--R-2.2.1 still not available as RPM
R-2.2.1 is still not available for Redhat Linux as an RPM on CRAN. It
is available as an SRPM. Can someone fill me in on why it takes so long
to make RPMs available? I would be happy to help make the RPMs for el4
and el3 if such help is needed.

Rounding parameter values in genoud(), Rgenoud package
I would like to limit the significant figures of the calibrated
parameters determined by genoud() in the Rgenoud package. Below is some
example output, where column 1 is model run number, columns 2-7 are the
parameter values, and columns 8-12 are model fit statistics. I would
like genoud to internally limit parameters to 4 decimal places as shown
in this output. It is clear that the function is

Parallel computing in R for dummies--how to optimize an external model?
I am trying to use the optimizing function genoud() with the snow
package on a couple of i686 machines running Redhat Linux WS4 . I don't
know anything about PVM or MPI, so I just followed the directions in
snow and rgenoud for the simplest method and started a socket cluster.
My function fn for genoud involves updating an input file for a separate
numerical model with the latest parameter
