Dear all, Has anyone written functions to compute (and ideally project / plot onto a plane) confidence ellipsoids for q linear model parameters, q > 2 ?

To Windows R users: The binary build of R that I uploaded on Tuesday contained errors in the compiled HTML help files and some of the PDF versions of the manuals. In particular, the index was missing from the CHM files, and the table of contents was missing from at least one of the manuals. I've since found the error in my setup, and have rebuilt the distribution. I uploaded it to CRAN

Dear R-users, Is there an easy way to avoid points one upon another when ploting rows and columns of 'dudi' objects ? Maybe there is a function in ade4 or in an other package, or maybe someone has his or her own function to do this (for example to automatically modify a little the coordinates of these points to get a readable plot ?). Thanks in advance. Best regards, Jacques VESLOT

Hello, I am a beginner in R programming and recently heard about this mailing list. Currently, I am trapped into a simple problem for which I just can't find a solution. I have a huge dataset (~81,000 observations) that has been analyzed and the final result is in the form of 0 and 1(one column). I need to write a code to process this column in a little complicated way. These 81,000

Please, forgive my ignorance on statistics, but I have a rather simple question concerning AIC. Small values of AIC mean good fit of the model. How about negative values of AIC? Is a model with AIC=0.5 considered to have better fit than a model with AIC=-500? I couldn't find anything explaining this in the documentation or any elementary statistics textbook that I have at my disposal. Thanks

I've put up a build of the current R-patched (and updated recommended packages) for Windows at http://www.stats.ox.ac.uk/pub/bdr/RWin/Rpre/SetupRpatched.exe This should be able to rename files on Win 9x (unlike the mid-May build) and can build packages accessing Rblas.dll. As ever, this is less tested than an official release, in particular only on Windows XP, but ought to have fewer
