Hi, I want to perform goodness of fit test for multinominal distribution. The easiest way would be to use Chi2, but the measurment errors are not normally distributed. I thought about using some bootstraping method to perform the analysis. How can I do it in R?

Hello, I've had a quick look on the list and can't find an answer to this niggle. Whilst debugging some code, I noticed that looping variables in R are not local to the loop as seams common in procedural languages. For example consider the following piece of code: for(i in 1:3){ cat(i,"") for(i in c("a","b","c")){ cat(i,"")

I have put a preliminary version of factanal in a package at http://www.stat.ox.ac.uk/pub/R/fa_0.1-1.tar.gz and would appreciate feedback. In particular 1) What else you might want. Please give precise references with algorithmic details, as that has been a major problem for me. 2) Some convincing examples of factor analysis. Most (literally) of the ones I have looked at are local maxima, not

I've compiled the 1.8.0 R on Solaris 2.9 and when trying to use plot command I get the Bus error and a core dump. Anybody experienced something like this? If yes, what should I patch? Janusz. [[alternative HTML version deleted]]

Dear List, I am looking for a possibility to fit a mixture model under R using maximum likelihood estimation. Venables and Ripley describe a solution working under S+ (in MASS, 3. ed., p. 263) which requires the D system function and deriv3. This solution does not seem to be portable to R or at least I do not realise how. Is there anyone who a) knows how one could make the MASS-method run under

Hello, I have two vectors x1 and x2 both in increasing order. I want to select the x1[j]th entry which is the max min of the x2[i]th entry. I can do this using if and for statements but is there a quick way to do it without running a loop? Thank you in advance, Pantelis

Hi, I am VERY interested in getting the xfig driver so that I can edit graphical output from R. Searching through the mail archives and reading documentation isn't helping. Is there or isn't there a working driver for this purpose. How can I get it? I tried looking at the development version of the tarballs, but I didn't find anything that looked promising in there. Also, does

I am interested in finding an R version of SAS "Proc Varclus". SAS's Proc Varclus implements an oblique cluster analysis based on principal components. How can I find out if R has a package that runs the same algorithm implemented in SAS "Proc Varclus"? Thank you, Mary Helen Black __________________________ Mary Helen Black, M.S.

I have moved from dovecot 1.x to 2.x and I have big problem with subfolders. When I'm moving subfolder with other subfolders is moving only main subfolder, without subfolders, example : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/dbox-Mails

Hi, I'll apreciate your guidance on how can I re-create the output from SAS PROC VARCLUS in R. I've found the varclus function in Hmisc. However, is it possible to use that function to compute for each variable the 1-R**2 ratio (this is the ratio of 1 minus the R-squared with Own Cluster to one minus the R-squared in the Next Closest cluster)? Thanks in advance for any help, Lars.

I am using R 1.3.0 on Windows 2000. For an experiment, I am wanting to find the most diverse 400 items to study in a possible 3200 items. Diversity here is based on a few hundred attributes. For this, I would like to do a clustering analysis and find 400 clusters (i.e. different from each other in some way hopefully). From each of these 400 clusters, I will pick a representative. I expect

Hi All, I'd like to build a package for the community that replicates the output produced by SAS "proc varclus". According to the SAS documentation, the first few steps are: 1. Find the first two principal components. 2. Perform an orthoblique rotation (quartimax rotation) on eigenvectors. 3. Assign each variable to the rotated component with which it has the higher squared
