[Env: Win XP] I've just upgraded from R 2.12.2 to R 2.13.1. As part of my upgrade process, I typically install some in-development packages from R-Forge that are not on cran. But for the first time, it doesn't work. e.g., > install.packages("p3d", repos="http://R-Forge.R-project.org") trying URL 'http://R-Forge.R-project.org/bin/windows/contrib/2.13/p3d_0.02-2.zip' Error in download.file(url, destfile, method, mode = "wb", ...) : cannot open URL 'http://R-Forge.R-project.org/bin/windows/contrib/2.1...

Hi, Can anyone guide me as to how I can add points to a p3d() plot from the onion package?? I want to plot points with different colors on the same 3D plot.? Perhaps I can do this without adding points but somehow directing the 'h' parameter to give different color to points based on a factor I assign to them? FYI, I can do this using using scatter...

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 all, sorry if it's obvious but I wasn't able to find a solution by myself. I have a text file filled with 3 colums representing xyz coodinates (i.e. positions) of an objects. Can I have in R a 3d plot representig my object' s positions? I guess that I can but I don't know how. Any help is much appreciated Thanks a lot -a- Andrea Valle DAMS - Facolt?? di Scienze

Dear Colleagues: I have 3 numeric variables (say x, y, z) in a data.frame and want to draw a 2D-scatterplot with the 3rd dimension as color, if possible without having to convert the whole thing to an appropiate matrix for image() manually. Can e.g. scatterplot3d do something like this? There's a function xyz.convert, but I couldn't find the way to use it properly. Sincerly,
