3d plots?
Hi all
I'm trying to create a three-dimensional wireframe-type plot,
much like the screenshot shown at
http://www.r-project.org/screenshots/volcano-persp.jpg
In my case, I'm trying to show a density estimate of
two-variable system, using the GenKern package. I've
used the image() and contour() to create a nice shaded plot,
but I've found a 3d plot is often easier for the

two perspective plots in in plot
Dear all,
I would like to put two perspective plots into one plot. The help page
for ?persp shows how one can add points and lines but not another
perspective plot.

z <- 2 * volcano # Exaggerate the relief
x <- 10 * (1:nrow(z)) # 10 meter spacing (S to N)
y <- 10 * (1:ncol(z)) # 10 meter spacing (E to W)

Problem in calling R functions from Matlab
Hi,
I wish to use R (version 2.13.1)?from within Matlab(ver R2009a) on windows XP plaform (on both 64 bit and 32 bit OS) . For this I have installed StatConnector (http://rcom.univie.ac.at/download/current/statconnDCOM.latest.exe) for calling R from within Matlab (R2009a) on Windows XP platform.

3d images
Hi,
The screenshots page of the R-project contains nice 3d images: "3d plot
of a surface" and "image and 3d plot of a volcano".
What packages were used to generate these images?
Or
What packages have 3d plotting capabilities?
thanks

overlaying points and lines on a surface3d rgl plot with axes
Hi R users and experts,
I am interested in learning more about the use of 3D plots. Specifically, I
want to add points and lines to a surface plot. And get the axes and labels
plotted also. Here is what I have tried with an example data set :
library(rgl)
vol2 <- 2*volcano # Exaggerate the relief
library(reshape)
mvol2 <- melt(vol2)
str(mvol2)
# First, persp and persp3d plots do not succeed

3-D plot of likelihood
Could anyone recommend a package for visualizing a likelihood function
of two scalar parameters? I would prefer a three-dimensional plot
similar to the kind Mathematica is known for, perhaps generated by a
package not specific to likelihood.

Persp and color
How can I control de "wrap-around" color behaviour in the persp
function ?
I am using something like :
persp(bb[1:100,2:97], col= rainbow(8,start=0.1, end=0.8)))
Depending on the rainbow length value I get several "wrap-around" blocks of
the selected color range...something that I wanted to avoid...
My idea is to use the color in order to make a separation from a

Computer Modern Fonts in R graphic
Hello all,
I am trying to use computer modern fonts in my r grahics. I tried to do,
as described here: http://www.stat.auckland.ac.nz/~paul/R/CM/CMR.html
but unfortunately, it does not work.
First of all I downloaded the cm-lgc package and the AFM and PFB-files
from the page and put them in my R working directory, so far, so good.
Then I tried to run the following code:

R-alpha: R 0.50.a1: small patches for graphics and image demo
Applying the following patches closes the following task (part 1 was
already taken care of).
TASK: New Problems
STATUS: Open
FROM: <Kurt.Hornik@ci.tuwien.ac.at>
New minor remarks:
* The documentation for `image' still has the old order z, x, y.
* Perhaps one should add `par(ask = T)' in the image demo?
* Perhaps one should save the original value

3-D scatter plot laid over Surface plot
Hello,
I have created a Fitness surface (persp()), with data that was created
by a tp spline procedure. Now I would like to superimpose a set (XYZ) of
existing points (from two different treatments) onto this surface.
I didn't come across any function or command that is able to do this in R.
Could somebody please help me in finding a solution to this problem
Thank you

pb with Date format using filled.contour
Hi R-help community,
Can anyone tell me why, while using :
x <- seq(as.Date("2001-01-01"),as.Date("2001-01-01") +
nrow(volcano)-1,1)
y <- seq(1, ncol(volcano),1)
when I plot the volcano matrix with that command :
filled.contour(x,y,volcano)
the graph has a Date format on X-axis, ok ...
... but when adding a contour plot to the filled contour, using this

Adding a distance scale to a plot?

I'm pulling my example out of "An Introduction to R: Software for StatisticalModelling & Computing" (see the R code around Figure 76).
I would like to add a scale to the image produced by the following code.? I would like to the scale to list the distance?and units:?

customizing color key with plot3D
Karline,
Thank you for your help. I discovered that in addition to including clim, I needed to omit breaks. This code uses one of your other examples as a starting point and works as intended:

Hello list!
I have a problem with the function 'persp'. I have a data set with the
variables
X -> The X coordenate of the insect
Y -> The Y coordenate of the insect
deep-> how deep the insect buried into the soil.
I would like to have a plot with a surface simulating the way the insect
buried. Is it possible? If I type

persp graphs
Hi,
I am doing my way on R, with much experimenting. So, I am trying to plot a 3d
graphic ussing "persp" and entering a data set (attached) of UTM coordinates
as x,y and a pH values as z. However when I try an error message comes out
telling that increasing x and y values are expected. Jus ordering the first
vector does not help, and, of course, order the first two independently

behavior of squishplot in TeachingDemos
Hi list,
I wonder if anyone has had this experience with squishplot() in the TeachingDemos package.
Taking the example from the ?image help page,
library(TeachingDemos)
x <- 10*(1:nrow(volcano))
y <- 10*(1:ncol(volcano))
layout(matrix(c(1,2,3,4),ncol=2,byrow=TRUE),height=c(2,1))
## 1st plot
op <- squishplot(range(x),range(y),1)
image(x, y, volcano, col = terrain.colors(100))

shading in image()
Is there a way to make a shading interpolation on an image plot?
Something similar to matlab 'shading interp', I think it is called Gouraud
shading.
What I want is to make a image plot look nicer. with image() it looks very
facetted, and I would like to make it look smoother.
I've tried with interp.surface() in fields package but it (obviously) makes
nan values at the borders and
