Multinomial Nested Logit package in R?
...note the model used by Schmidt and > Strauss (1975), while > multinomial logit is used as a synonym of conditional logit.

read.spss and encodings
Hi! I'm having trouble with importing spss files containing non-ascii characters (R 2.4.1, debian linux, i386). To reproduce: Download the following file: http://statmath.wu-wien.ac.at/data/spss/de/comphomeneu.sav require (foreign) Sys.setlocale (locale="C") read.spss("comphomeneu.sav")$ARBEIT[1] # prints: # [1] im B\374ro # Levels: im B\374ro zuhause \374 of course is actually a u-umlaut. However, I guess in the C locale it's not expected...

vignettes and papers
Hello everyone Lots of my packages have been the subject of journal articles either in JSS or Rnews or (in one case) elsewhere. I would like to add these articles to my packages as vignettes. Reproducing the papers exactly requires a number of files [such as style files or PDFs] to be included in the inst/doc directory to pass R CMD check. A vanilla .Rnw file seems to be a good idea, but

AID / Tree Analysis in R
Dear Colleagues, I've been looking for a function that can perform a tree analysis, similar to CHAID or QUEST. The key point is that in this case the variables are not binary but nominal (10 different values), so "tree" (from the tree package) won't work. Does anybody know help?

Buglet in qbeta?
Hi, I sometimes play around with extreme parameters for distributions and found that qbeta is not always monotone as the following example shows. I don't know whether this is serious enough to submit a bug report (as this example is near to the limitations of floating point arithmetic).

Interface for package supplied random number generator
Hi, As you probably know, there is a problem with the interface for adding uniform random number generators in R (see by article in R News 5/2, November 2005). There exists a mechanism called "user-supplied" that allows users of R to run their own generator in R. However, there is no such mechanism for package writers. Those who want to add their own generators abuse
