I am curious whether anybody has or is developing this capability within R. I have not found any software yet that has this capability and I am not sure whether it is too new a method and nobody is actually using it, or if there are other means to get the same analysis that I do not know of. Any information regarding developments or use of this method would be helpful. Melanie Edwards

...components analysis (PCA) and hierarchal cluster analysis. I have also been experimenting with glyph representation, k-means clusters, and similar procedures as documented in MASS. More recently I have been experimenting with Independent Components Analysis (ICA). Another commonly used procedure is polytopic vector analysis (PVA), a procedure for which I have no implementation in R sand so I have not tried it out. My question is can anyone suggest : A) Other procures in R that I may have missed and should investigate B) Your experience and/or hints for using ICA and presenting the results C) An impleme...

Dear useRs, I'd like to announce a new package called geozoo, short for geometric zoo. It's a compilation of functions to produce high-dimensional geometric objects, including hypercubes and hyperspheres, Boy's surface, the hyper torus and a selection of polytopes. For a complete list, as well as images and movies, visit

Dear R helpers I have a question regarding the constrainOptim. I'm coding the nested logit and would like to set a bound of rho to (0,1] as an extreme value distribution where rho = exp(lambda)/1+exp(lambda) I wonder if I can do that directly in optim (say rho > 0 & <= 1) or need to use constrainOptim I read the help but still don't know how to set ui and ci Thanks, June

The FreeBSD Project is pleased to announce its participation in the Google "Summer of Code" program designed to introduce students to open source software development. The FreeBSD Project received over 350 applications, amongst which 18 projects have been selected for funding. Unfortunately, due to the limited number of spots available, we were unable to fund many first rate

I already looked into implementing something like Graphite for LLVM. However just recently, so I have not released any code yet. As soon as some code is

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems
