similar to: rgl.postscript() failure when saving a scene

Last week I asked about data ellipses with rgl:::ellipse3d() with lines showing the principal axes. (The goal is a visual demonstration of PCA as a rotation of variable space to component space.) I was trying, unsuccessfully, to use princomp() to generate the PCA axes and plot them using segments3d: > > PC <- princomp(trees) > > sdev <- PC$sdev # component standard

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

I have a 3xN matrix of parameters obtained from N regressions where the 3 parameters are jointly statistically significant. I would like to reproduce a 3D confidence ellipsoid projecting 2D ellipses onto the XY plane as in Figure 5.2 in this

Dear list, I'm trying to visualise some ellipsoidal shapes in 3D. Their position, axes, and angular orientation can be arbitrary. I saw an ellipse3d function in rgl; however it is heavily oriented towards the statistical concept of ellipse of confidence, whilst I am just concerned with the geometrical object. Below is my current implementation. It is quite slow when creating many shapes, so

Hi I'm trying to make a 3d plot showing a point cloud, the corresponding data ellipse and the principal axes of the ellipse as vectors. library(rgl) data(trees) cov <- cov(trees) mu <- mean(trees) plot3d(trees, type="s", size=0.5, col="blue", cex=2) In this step, an extra box is added. I've tried using box=FALSE, but it has no effect. # how to avoid the

hi can somebody please help install paltalk scene, i have tried many threads here and in ubuntu forums withous success thanks in advance

Hi the list, As far as I understand, a possibility to create a "scene" is to provide a list of triangles to the function makeTriangles. Is there also a way to turn the data that are used by "plot3d" into a scene? I would like to write: --- 8< --------- M <- matrix(runif(12),4) plot3d(M) ### Some secretes operations that turn M into a Mscene Mscene <-

This is an fairly easy tutorial and I hope you enjoy it! Have a try! Here is the preview of the final result: alternative version I have: (adjusted the colour balance and add two planets into it) OK Let?s get started! To complete this tutorial, you will need the following stocks: Dancer Nebula Texture 1 Nebula Texture 2 Step 1 Load the dancer image into Photoshop and resize the image to 1200px

Hi, I have been using Miranda (version 0.7.19, latest that can handle MSN) Lately i have get some problem, i cant see peoples avatars and when i log in i get about 4-7 errors massages. Im running Arch now, before that i was using Ubuntu and with some help with winetricks then this problem was gone. I?m using the latest version of Wine and winetricks. Terminal output: Code:

Hi everyone, I am having problems with "oopses" since I introduced HTB on my company''s PC-based routers. It seems that only routers with high network load are affected. The average network load on the two most problematic routers are 10Mbps in/out and 2.5Mbps in/out. The other machines with less than 1Mbps average traffic seems unaffected. We have been getting oopses on

Hi, Recently on trunk, the ovlaps list for a register got a dual entry on my target, which caused the RA to crash. Reg Subreg1 Subreg b Subreg2 Subreg b I have a register with two subregs that have subreg b in common. This causes the SuperReg to appear twice in the ovelaps list for Subreg b. As this causes a register allocator to crasch (it evicts a register, and then inremenets

Hi list! I'm currently trying to get a program called Polydoc to run under wine. It is a kind of database app, for text databases. For some reason it uses many ActiveX controls. So far all seems to be Ms "standard" controls. But the program will not run. Anyone have a tip? I'm going to test with a native ole32.dll among things. Cheers, -- Martin Widmark AB TakeIT

The GUI tool to set date time works great when your running X or whatever, but what is it really doing in the background? How do I setup automatic time synchronization from the command line? Reference the GUI setup doc at: http://www.centos.org/docs/5/html/5.1/Deployment_Guide/ch-dateconfig.html

Here is a patch that fixes distortions that appear during scenes with no motion. Tbe problem was that UpdateFrame() was not being called when a MotionScore of 0 was computed. Since UpdateFrame() was not called the buffer returned by theora_encode_packetout() would be the same buffer that was output for the last frame that had a non-zero MotionScore. This is obviously incorrect behavior. I've

Hi all, I have a dataframe that includes data on individuals that are distributed across multiple rows. I have aggregated the data using ddply, but I have columns in the original data frame that are factors ( such as sites "A", "B", and "C") that I would like to include in the new data frame. I have done this in a clunky way using match() and a loop, but am

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

Dear list, I've generated a list of 3D coordinates representing ellipsoids in arbitrary orientations. I'm now trying to obtain a 2D projection of the scene, that is to draw the silhouette of each object on a plane (x,y). The only way I could think of is to compute the convex hull of the (x,y) coordinates of each object and use this as the outline of the object. This is clearly

We have a location that is having a really odd issue. We have a sangoma POTs card. We are running software echo cancellation with the card (through asterisk) to try to eliminate some major echoing problems. I've turned on both EC and echotrain, which seemed to have gotten rid of the echo for the most part. However, we are now running into an issue where the outside caller hears a star wars
