Dear R users: is there a package, similar to varclus in SAS or varclus in S, ported or written for R? Also, is there any other package in R that was designed for grouping the variables under different measures of distance (in cases where data is non-Gaussian, autocorrelated, and so on).

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

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

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

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

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 all, firstly I would like to say I am a beginner user for R and also naturally a new member of this mail list. This means I have newer read previous mails before. I need a small help for my analysis. I want to perform a multinominal logistic regression for my data set. But as I told before I am a beginner for R and I couldn't find the code for multinominal logistic

Hi, I have data in form: label, x, y. How can I make a scatter plot from the data, so that the label will be just next to the x, y point?

I use mnp to run a multinominal probit regression model, but the summary doesn't contain the model statistics, such as the log-likelihood and degree of freedom, for the assessment of the goodness-of-fit of the fitted model. Is there any way that I can generate these statistics for the fitted model in R? Many thanks in advance! SC

I'm trying to fit a multinominal logistic model using package mlogit. I have 15 independent variables. The code looks like this: m<-mlogit(score~0|f1+f2+f3+f4+f5+f6+f7+f8+f9+f10+f11+f12+f13+f14+f15, data, reflevel="1") And it gives the following error message: Error in parse(text = x) : unexpected ')' in "score ~ 0 + alt:(f1 + f2 + f3 + f4 + f5 + f6 + f7 + f8 + f9

dear professor: I am a doctor of urinary,and I am developing a nomogram of bladder tumor.Now I have a problem about this. I have got the result like this through analysing the dataset "exp11.sav" through multinominal logistic regression by SPSS 17.0.(the Sig. is high,that is good ,it is just aexperimental data ) Parameter Estimates Ya B Std.

Gracias Carlos. Hasta donde yo entiendo si las hay: El argumento family puede ser: "gaussian" (for minimizing squared error); por lo que tiene que ser numérica "bernoulli" (logistic regression for 0-1 out-comes); binaria por narices "poisson" (count outcomes; requires the response to be a positive integer); numérica también, pues. La única podría ser

I have moved from dovecot 1.x to 2.x and I have big problem with subfolders.

Hola de nuevo. Se me olvidaba la principal razón para utilizar gbm.step del paquete dismo. Como sabéis, los boosted si sobreajustan (a diferencia de los random forest o cualquier otro bootstrap) pero gbm.step hace validación cruzada para determinar el nº óptimo de árboles y evitarlo. Es fundamental. La opción que me queda, Carlos, es hacerlo con gbm, pero muchas veces, y usar el
