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,

Getting default aspect ratio from lattice
How can I get the value of the aspect ratio that is used in a lattice
plot? In a levelplot for instance, the native units per cm of my x and
y axes are different, and I need to know the aspect ratio so that I can
correctly plot vectors. I know how to set the aspect in a high-level
lattice function but I can't quite figure out how to get it. I would
like call to levelplot() without printing

Unsightly lines from x*y grid in levelplot with Postscript
When I generate levelplot figures with Postscript, the lines from
the underlying grid (i.e., the x and y in z ~ x* y)
show up as faint white lines in the output. If I have a dense grid,
the lines wash out the contour colors. I can avoid the problem if
I use png instead, but that brings up other problems. Any
ideas for how I can get Postscript to not show those lines around
the cells?

polygons around clusters of identically valued nodes in levelplot()
I'm looking for a way to plot lines on top of a levelplot(),
where the lines are borders between cells of different values.
The clines() function provides contours suitable for continuous
data. I am dealing with discrete values, spatial clusters of nodes
where each cluster has an integer value, and I want to plot the
borderlines between these areas.
So, in a levelplot having nodes with

Different scales for keys in lattice levelplots
Can anyone tell me how to obtain a custom scale for
the colorkey in each levelplot of a lattice? I am using
lattice and levelplot to plot z = f(x, y) for multiple z
variables. x and y values are the same across plots, but
units for z are different and therefore I need to create
a custom scale for each plot's key. It follows that I need
to place each plot's key inside that plot's

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.

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

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.

Getting polygons from contiguous grid cells having same value in sp
I have been using the sp package to deal with gridded data. I would
like to know how to extract the vertices (x,y) of polygons that outline
areas of like-valued cells in a grid. Here is a simple 3x3 grid:
2 2 1
1 2 1
1 1 3
x <- c(1,1,1,2,2,2,3,3,3) # define a 3 x 3 array of points
y <- c(1,2,3,1,2,3,1,2,3)
h <- SpatialPoints(cbind(x,y)) # make these an sp object of the points

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

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

is fine.

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

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.

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

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

How to create an R RPM from source
I use some computers that run older versions of Redhat Linux such as
EL3. RPMs for the current version of R are no longer provided via CRAN
for these older operating system versions. How can I compile my own RPM
for the current version of R, which I could then use to install R
quickly and easily on multiple machines? Perhaps the answer to this
would be a useful addition to the manual R

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?

lattice::panel.levelplot.raster too picky with unequal spacing
Dear all,
I got a couple of warnings using panel.levelplot.raster,
In panel.levelplot.raster(..., interpolate = TRUE) :

although I was quite sure my data were equally spaced (indeed, I
created them with seq()). A closer look at the source code reveals
that the function tests for exact uniformity in grid spacing,
