Lattice wireframe: How to avoid drawing lines around polygons when using shade=TRUE
I am using wireframe from the lattice package, with the shade option set
to TRUE. When I output to PDF or Postscript, a line gets drawn around
each polygon of my surface which causes ugly Moir? effects and doesn't
make sense in my application (think the plot of Maunga Whau--gridlines
don't make sense). This does not happen when I display on the screen--
then I just get the surface as

creating pdf of wireframe
Dear R list,
I have written some code to produce several wireframe plots in a panel. They
look good, but when I try to create a pdf, many (but not all) of the details
I have specified are not reproduced. For example, the line width I have
specified is not reproduced, and neither are the font sizes for the axis
labels. I'm an R novice, so I could really use some guidance.
Here is the code I am

coloring wireframe plot with independent/separate matrix of color values.
Dear R Users,
I am trying to plot a matrix (a Digital Elevation Model) using wireframe
[lattice] and color that matrix based on a separate/independent matrix of
the same resolution (both have the same number of rows and columns) as the
DEM. More specifically I would like to plot a DEM using wireframe and
color each cell/tile based on interpolated surface temperature
measurements. Within the

Wireframe (lattice) questions
I have a few questions on formatting wireframe plots:
1. How can I remove (or at least "white-out") the border on the plot?
(I.e., the 2-d box around the whole plotting area, not the 3-d cube). I'm
willing to hack the code if necessary.
2. Is it possible to suppress plotting of all sides of the cube except
for the axes?
3. Is there a reliable way to print expressions in

Q: R 2.2.1: Memory Management Issues?
Dear Developers:
I have a question about memory management in R 2.2.1 and am wondering if you would be kind enough to help me understand what is going on.
(It has been a few years since I have done software development on Windows, so I apologize in advance if these are easy questions.)

wireframe question
Hi,
I'm probably being dense, but could somebody tell me how I can get tick marks on the axes of my wireframe plot to show up?
This gets me a beautiful looking plot, but no ticks:
wireframe(z ~ x * y, data, drape=T, colorkey=F)
Thanks in advance,

wireframe and par(mfrow)
Hello List,
I have some plots with the wireframe() function, and I'd like to
display them in a single jpeg file. I know that par(mfrow=c(x,y)) will
divide my display window in x rows and y columns, and although this
works with plot(), it looks like it's not working with wireframe.
here's my code:

Changing direction of an axis in cloud or wireframe plot
Is there a way to change the direction in which an axis is plotted in
cloud/wireframe?
For example, for the following code:

g$z <- log((g$x^g$g + g$y^2) * g$gr)
wireframe(z ~ x * y, data = g, groups = gr,

Trouble with drplot
Hi, I am a newbie with R, so I hope my question isn't too stupid. I am trying to generate dose-response curves using the "drfit" package. I have formatted my CSV files to the correct format, and have no trouble running drfit to get a summary of my data. The problem is that when I try to use "drplot" to graph my data I get an error.

wireframe zlim option
Hello,
I would like to plot a wireframe of a function which is defined on the
unit square using the lattice library (for trellis-like plots). The plot
contains z-values of about 100 (only in the neighborhood of zero) although
most of the z-values are in the range of -let's say- 0 to 10. If I
evaluate this function on an equidistant grid of 25 points on the unit
square the plot quality is not

grayscale wireframe??
I need grayscale formatting for a wireframe.
The only col.regions that I can find are color palettes are all colored:
rainbow(n, s = 1, v = 1, start = 0, end = max(1,n - 1)/n,
gamma = 1, alpha = 1)
heat.colors(n, alpha = 1)
terrain.colors(n, alpha = 1)
topo.colors(n, alpha = 1)
cm.colors(n, alpha = 1)

Controlling (number of) wires in wireframe
Hi,
I would like to plot a wireframe (library: lattice) of the function f
(x,y)=x*y where x and y are equally evaluated between 0 and 1.
When one uses the option drape=TRUE then each "square" between the
"wires" (lines that build the surface shape) gets a certain color. A
perfect wireframe plot of a continuous surface would be, if you

Lattice: use levelplot as panel for wireframe
Hi,
I want to draw a figure similar to http://dsarkar.fhcrc.org/lattice/book/images/Figure_13_07_stdBW.png
from http://lmdvr.r-forge.r-project.org/figures/figures.html (figure
13.7) . However instead of using a contour plot as a panel for the
wireframe I want to use a levelplot. Can somebody help me with this?
Thanks in advance for any help,

layout(matrix(c(1,1,2,3), 2, 2, byrow=TRUE));
so that the frst plot spans the both columns in row one. Now I'd like to magnify the fist figure so that it takes 20% more vertical space (i.e. more space for the y-axis). How would I do this in R?

Lattice wireframe or cloud plot with different colours by a group
I have a question about wireframe 3-D plots and how to apply colors. I have

flows based on their height. I would like to produce a wireframe plot that
colors the graph based on the flow code, i.e. I would like high flows to be
red, medium to be green and low flows to be blue. Here is some sample data

3D Graph Surface and single points (eg wireframe with points)
Hallo!
?
I just want to make a 3D plot of a surface of a cone and want to plot some single points around.
?
I tried wireframe but cannot find how to plot single points
?
I tried scatterplot3d but there the surface is not simple to plot. And: How can I rotate the point of view by the z-axis
?
I tried persp3d but how can I add some single points?
