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. rgl_0.92.879 car_2.0-12 R version 2.15.0

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

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, //M

3d scatterplots of more than 1 data set
hi, i am need to plot two or more sets of data in a 3d scatterplot, each set with different color. 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 it. i need to be able to rotate the axes, and

question on rgl.surface
I'd like to use rgl.surface (or some other function if more appropriate) to create a horizontal and vertical transparent grey slice (plane) running through both the x and y origins and extending across the z axis, i.e. the 3-d equivalent of the normal 2-d coordinate axes we are all familiar with. The examples for rgl.surface are a bit more complex than what I need and I am having trouble

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

Plotting a 3D surface
Hi Does R have a function or has someone written a function to draw a 3d surface from a scatter plot of values using either ksmooth or locpoly. OR a transform function a that merges x relation z and y relation z to (x,y) relation z? I tried out scatterplot3d but it seems it would take a bit of work to get scatterplot3d to draw a curved surface. Lawrence

Is there a regression surface demo?
Hi All, Does anyone know of a function to plot a regression surface for two predictors? RSiteSearch()s and findFn()s have not turned up what I was looking for. I was thinking something along the lines of: http://mallit.fr.umn.edu/fr5218/reg_refresh/images/fig9.gif I like the rgl package because showing it from different angles is nice for demonstrations. I started to write my own, but it has

R Project for measurement of earnings management
Hello there, My name is Alireza. I am interested in utilizing R-program for measurement of earnings management (accounting related issue). However, there are two source programs which should be used simultaneously with the R-program to be able to measure earnings management. Previously (i.e. in year 2006) I could obtain these two source programs off the R-Project website (i.e.

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? scatter3d(all.pca$x[,2],all.pca$x[,3],all.pca$x[,1],

How to display an image on RGL plot?
Hi all. It's been a long time since I wrote to this list. Glad to see the R project well and working. I am working with a 3D plot similar to this: http://old.nabble.com/file/p26525177/rgl-device.png rgl-device.png The underlying picture is a JPEG image, loaded with the rimage package and coerced to the matrix. Spheres denote control points, collected from this picture and must be

rgl.postscript() failure when saving a scene
Dear all, I write to the community to know if other people expierenced the same problem. I want to save a rgl scene where I plotted a 3d cloud of spheres whose radius is set proportional to a given variable and coloured by another group variable and with 95% ellipsoids for distribution of any group. I had no problem at all for coding but I had two problem when saving the scene (in any format)

scatter3d with groups
Dear R users, I'm currently visualizing my data using scatter3d from the "Rcmdr" package. I have data points which can be separated in two classes. Data points from class 'A' should be colourised red and data points in class 'B' should be colourised 'blue'. No matter what I try, the data points are always blue. I attached a (very) minimal example to

shapes in rgl
Does anyone have a way of producing solid shapes other than spheres in rgl? I am using rgl to produce a simple visualisation of a forest model results using "lollipops". Its just a bit of fun, but as many of the trees are pines I would like to depict their crowns as cones. If there is a solution I need it to work under windows. Here is the example. library(rgl) library(misc3d)

Print plot to pdf, jpg or any other format when using scatter3d error
Hi, I have been trying to output my graphs to a file (jpeg, pdf, ps, it doesnt matter) but i cant seem to be able to get it to output. I tried a 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 screen without any problems, but when it comes to writing them to a file i cant make it work. Is there any

rgl.snapshot() on Vista
Dear Daniel (and Duncan): back in January you reported that you were having trouble saving an rgl movie on Vista. I don't know if you ever got that resolved, but a student of mine is now having a similar problem, not specific to dynamic graphics (which would have to be a problem outside of rgl anyway). He may report more on the symptoms, but essentially rgl.snapshot produces black or funky

Slowdown when copying large files
I am currently investigating using samba on a Linux box to provide file server services on our NT LAN (I'm a bit sick of NT doing dummy spits on me). I'm running RH5.1, and have just upgraded samba to samba-1.9.18p8-51.3 (using the rpm from http://samba.anu.edu.au/samba/ftp/Binary_Packages/redhat/RPMS/5.1/samba- 1.9.18p8-51.3.i386.rpm) The setup includes several NT servers, one set up as
