scatter3d() model.summary coefficients?
Hello All,
I am a R newbie and am probably misinterpreting something really
obvious...
In the Rcmdr package there is a scatter3d() function that can fit a
curve and also provide coefficients for the model. If I'm understanding
this right, I think it's calling the lower level stats package function
lm(), which is the part that actually does the curve fitting.
Anyway, what has me

Is there a function for scatter3d with Categorical responses?
Hello,
I'm working with a series (30+) of hydrologic metrics and 10 vegetation
communities and I need to determine which of the metrics provide the best
separability for each of the vegetation communities. The hydrologic
metrics are highly correlated, therefore the need to reduce the number of
them considered is critically important.
I've been looking at the scatter3d function in the

scatter3d: problem with spheres-color
Dear List,
I don't get scatter3d to color the sheres according to the '|' argument.
library(car)
scatter3d(prestige ~ income + education|type, data=Prestige)
The spheres on my screen are all colored the same and they are not
conditional on Prestige$type.
On the other hand: Fit3d and Ellipse3d are colored according to the
group argument.

Rcmdr scatter3d
Hi, I am using the scatter3d function in Rcmdr to plot
the first 3 principal components, I have a grouping
variable of 2 groups, and tried to plot points with
different colors, somehow I couldn't change the
default colors of the 2 groups (blue and green)by
using option points.col=c('red','blue'), what's the
problem here?

Remove squares from scatter3D
Dear All,
I?ve been trying to find an option to scatter3D from rcmdr to remove the individual points from the plots but to no help so far. Removing the residuals is easy, but I cannot find a similar point option. Is there such an option that can be set to FALSE?
Best,

I have been trying to output my graphs to a file (jpeg, pdf, ps, it

few things but none of them worked and am lost as what to do now. I am
using the scatter3d function, and it prints out the graphs on tot he

Rcmdr and scatter3d
Hi folks,
I'd like to use scatter3d (which is in R commander) to plot more than one
dataset in the same graph, each dataset with a different color. The kind
of stuff you would do with "holdon" in Matlab.
I read a recent message that was posted to this list with a similar
problem, but I couldn't understand the reply. Could someone give me one
example? How do you plot subgroups

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
use the groups = ...

Surface plot for polynomial regression
Dear R-experts,
my goal is to visualize the following polynomial regression as a 3D-surface:
Z = b0 + b1*X + b2*Y + b3*XY + b4*X^2 + b5*Y^2
I believe that a solution to this problem may be of interest to a wider
range of scientists because the problem is a derivative of a more general
problem, i.e.: how to describe the relationship between one dependent
variable and the DIFFERENCE between two

Diagnosing trouble with R-2.0, Fedora Core 2, and Rcmdf
Greetings, R-help!
On 2 Fedora Core 2 Linux systems, i've completely erased the previous R
and all packages and then installed R-2.0 and installed fresh packages.
In using Rcmdr, I see some trouble and I wonder if other people see this
and if it is due to the tcl/tk, or R, or Rcmdr. (If readers have not
yet tried Rcmdr, I recommend it not just because of the GUI it provides,

Smoothed 3D plots
DeaR list,
I'm trying to represent some information via 3D plots. My data and session
info are at the end of this message. So far, I have tried scatterplot3d

persp3d (rgl), persp (graphics) and scatter3d (Rmcdr) but any of them gave
me what I'd like to have as final result (please see [1] for a similar 3D

Transform plot3d grafics in to executable files
Hello,
I did some nice grafics using plot 3d and scatter3d. Is there a,
hopefully not too complicated way, to transform these dynamic,
three-dimensional and interactive grafics in a kind of
executable file? I want to show and send them via e-mail to projekt
partners who don`t use GNU R and who are not used to do programming.
So the result should be quite comfortable to execute for them in

transparent surface in rgl
Hi all
I am a complete newbie to this list (just subscribed) and a newcomer to
R (an S user from olden times). I have been using scatter3d to create a
3d scatter plot with surface. The graphic is created within the rgl
package and I have used rgl.postscript to export it so I can generate a
publication quality image. My problem is that the plotted surface is no

lines on persp plot - proper depth ordering
Hello R-help!
I am trying to draw series of lines in 3d, and I am not sure how to get the
depth set up properly - lines that are in front of other lines appear to be
behind and vice versa. I've been doing this by first generating an empty
persp plot, then adding lines via the data into trans3d followed by lines
(this is probably a bad approach, but it was the first one I could get
working).

3d scatterplots of more than 1 data set

i am need to plot two or more sets of data in a 3d scatterplot,

i tried Rcmdr, and the 3d scatterplot facility, based on rgl. that
is what i need. but i cannot seem to code different sets of data
differently. any help will be very helpful.
i tried scatterplot3d, but it is difficult to get the right angle in

Scatterplot3d model reporting question
I've used the scatterplot3d function to graph some data and had it
graph a "smooth" fit. Is there a way to actualy find out the function
of the surface? I've looked through the help and figured out how to get
it to report the following:
Family: gaussian
Link function: identity
Formula:
y ~ s(x, z)
Parametric coefficients:
