plot3d, wireframe, persp help
Hello,
I am trying to get a surface plot of a data set that looks like the following,

From my homework, the persp function only works with evenly spaced data points with the z data beeing in a matrix. my data is not in that format.
the wireframe fxn gives me an error,

3D-plotting a 2D-matrix that contains z-values (3rd dimension)
Hello,
say I have a 2D-matrix (indexed by x and y), which contains
z values, which I want to plot over x-y.
Either dotted, or if possible as a landscape.
I tried around with persp and plot3d (from rgl)
and persp3d (from rgl).
I sometimes get something that looks good and a while later, when
trying some new data I need to worry about that again.
Is there something lika a convenience function

change pch in 3dplot, export graph
Hello I was wondering if anyone has been able to change the pch value for
points in 3dplot()? I am able to change point colors just not symbol types.
I have included a portion of my code below. I realize this won't work
outside of my script, but thought, maybe there is something obvious that I
am doing wrong. Also is it possible to utilize the interactive feature of

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

adding 3D arrows to 3D plots
Greetings,
I would like to add 3D arrows (i.e. arrow-headed vectors linking X1Y1Z1 to X2,Y2,Z2) to a 3D plot; ideally the sort of plot that can be rotated interactively. Is this possible using plot3d, or another 3d plotter in R?
While it is easy to draw segments in plot3d (e.g. below), I haven't figured out how to add arrow heads, or to create 3d arrows from scratch.

3d Scatterplot using rgl
Hi,
I am trying to plot a 3d scatter plot using the rgl package but am having trouble.
I have a matrix containing x, y and z co-ordinates and a fourth element related to a count variable.
I would like to plot the points using plot3d with the sizes of the points related to the fourth element in the matrix. Is this possible with plot3d or do I need to use something else?
I include a small example

save 3dplot to file
I think it is an easy question but i haven´t found a solution since I
am r beginner.
I did this
plot3d(PCoA, type="p", col=rainbow(1000),size=5)
text3d(PCoA, text=Nam)
How can I save it including the labels to a jpg-file?
Thanks in advance.

Correct NAMESPACE approach when writing an S3 method for a generic in another package
Dear List,
In one of my packages I have an S3 method for the plot3d generic
function from package rgl. I am trying to streamline my Depends
entries but don't know how to have
plot3d(foo)
in the examples section for the plot3d method in my package, without
rgl being in Depends.
Note that I importFrom(rgl, plotd3d) and register my S3 method via
S3Method() in the NAMESPACE.

rgl.postscript() failure when saving a scene

3D scatter, groups, RdbiPgSQL...
hello,
I wish to create some 3d scatter diagrams visualising different grouped
data set by a given field in the database. I tried the scatterplot3d
package, as well as the plot3d and scatter3d functions (both within the
rgl resp. Rcmdr package). My first question is, whether is it possibe to
group data in the scatterplot3d and plot3d, because I did not succeed to

greek letters in rgl plot3d
Dear RGL experts,
I haven't been able to add greek letters to my rgl plot3d.
I have tried "expression" with no success.
Here is the interested bit:
> library(rgl)
> cb <- cube3d()
> plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5)
The expression(alpha) appears as "alpha", rather than as a greek symbol.

plot3d con library(rgl)
Buenas tardes. ¿Sabe alguno de vosotros cómo indicar la variable con
la que identificar los puntos con plot3d?
library(rgl)

Las muestras pertenecen a una de dos categorías, según la variable
"Family", pero no sé cómo hacer que me las represente de diferente
color.
Gracias,

Writing my 3D plot function
Hi all,I had a question last week on asking for a function that will help me draw three different circles on x,y,z axis based on polar coordinates (Each X,Y,Z circle are coming from three independent measurements of 1-360 polar coordinates). It turned out that there ?is no such function in R and thus I am trying to write my own piece of code that hopefully I will be able to share. I have spent

rgl package don't draw points with a color over points with another color
I want to plot points with different colors to show different
selections of points in a 3d plot.
My problem is that if I plot a red point at a location where already a
blue point was plotted, than the point is still blue.
Is there a parameter or so which can be used to draw over a existing point?
Example:
> require(rgl)
> open3d()
> plot3d(a<-c(1,2,3,4,5),a,a,type="l",

Adding Text to a persp plot using specific coordinates

I'm experiencing some hassle to add some text on a persp plot...
Here is the code to generate the persp plot:
