question about cloud() in lattice package
Hi all,
I have been previously been using scatterplot3d package to create some graphs but unfortunately it does not allow me to rotate the
plot on all three axis. The cloud() function in the lattice package does allow me to do so. When I was using scatterplot3d I was
using a script (Shown Below) to calculate the mean, quartiles and range limits for all three axis and I was representing that on the

help debugging segfaults
(Sorry for the cross-post--- I wasn't sure which list is more
appropriate...)
Hi everyone,
I've run into segfaults when using my randomForest package on large dataset
(e.g., 100 x 15200) and large number of trees (e.g., ntree=7000 and
mtry=3000). I'm wondering if anyone can give me some hints on where to look
for the problem.

can't find array overruns (was: help debugging segfaults)
Dear R-devel,
Last week I got several responses to my question about debugging segfaults
in my code (original post below). After I changed the S_alloc() calls to
Calloc()/Free(), the symptom was gone, but I was told to keep looking. So I
did:
o Switched to Calloc/Free. Electric Fence did not find any problem.
o Put assert(index < bound); assert(index >=0); everywhere in the C routine

An "R is slow"-article
Hi all,
Reading the wikipedia page on R, I stumbled across the following:
http://fluff.info/blog/arch/00000172.htm
It does seem interesting that the C execution is that much slower from
R than from a native C program. Could any of the more technically
knowledgeable people explain why this is so?
The author also have some thought-provoking opinions on R being
no-good and that you should write

transparency of one layer in multiple wireframe plot
Sorry sending this again - is anyone familiar with multiple transparent wireframe plots?
I already checked the ?wireframe, but with no examples and as newcommer its hard to find out a correct code.
If we set drape=F in the example:
g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2)
g$z <- log((g$x^g$g + g$y^2) * g$gr)
wireframe(z ~ x * y, data = g, groups = gr,

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

wireframe color

but need different colors for different graphs.
Code is:

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,
Kind regards,

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 graph: black and white shading instead of color
All,
The code below produces a color 3D graph. I'd like to make it black and
white shading. I tried setting col.regions to FALSE but this just made it
completely white. I want the graph to look exactly as is, except black (or
grey) and white shading. Is this possible?
Cheers,
David

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,

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 <- expand.grid(x = 1:10, y = 5:15, gr = 1:2)
g$z <- log((g$x^g$g + g$y^2) * g$gr)
wireframe(z ~ x * y, data = g, groups = gr,
scales = list(arrows = FALSE),
drape = TRUE, colorkey = TRUE,
screen = list(z = 80, x = -60))

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

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)
The code follows:

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.

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?
?
Example:
?
