add one point to contourplot()
Hi All,
I want to add one point to contourplot(). I used contourplot() in my code like
contourplot(z ~ a + b |c, data)
I understand there is plot.axes argument for filled.contour(), but it did not work for my code. I also tried plot() and text() for contourplot(), but got this error: "plot.new has not been called yet"
Any suggestion for adding a point in contourplot()?
Thank you very

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

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

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

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?

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.

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

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

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

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 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.

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

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?

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

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:

Color schemes that work for people with color-deficient vision
A recent article in the earth science literature cited below and available at

points out that rainbow color schemes and mixtures of green and yellow
can be troublesome for people with color-deficient vision.
The authors propose alternative schemes that can be viewed and downloaded

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
