Dear R users, I m quite a novice in using R for factor analysis and I would need some help to choose the right function. I have a contingency table and I would like to perform a Correspondence analysis on this table, followed by a hirarchical clustering of my variables projected in on the first principal components. Here are my question : - what is the more appropriate function to do so ...

Hello ... I tried to generate .fig figures with R, using the xfig() function ...When I open the figures using xfig software under linux ... the foreground color change strangely ... whereas when I display the same figure in R or when I saved it in using postscript() function there is no problem. Any idea about the behavior of the colors when using xfig ?? Thanks in advance Christophe Grova

I am playing with the a 1-way anova with and without the "-1" option. I have a simple cooked up example below but it behaves the same on a more complex real example. From what I can tell: 1) the estimated means of the different levels are correctly estimated either way (although reported as means with the -1 and as contrasts without the -1 as expected) 2) the residuals are

I've downloaded R for windows (9.0.1) and it is great! I've converted all my lecture notes for my GLM course to run on R (they are available on my web page below). I must admit I particularly like the default contrast options, which are identical to GLIM. Also I like the gl function - very useful! I have a couple of questions/bugs: 1. predict.glm doesn't work, but predict.lm does -

Hello everybody, Is-it possible to include GSL library in the .C Interface?

Hello, I built 4 mixed models using different data sets and standardized variables as predictors. In all the models each of the fixed effects has an associated random effect (same predictor). What I find is that fixed effects with larger (absolute) standardized parameter estimates have also a higher estimate of the related random effect. In other words, the higher the average of the absolute

Hello, I am looking for references about mixed models built on rank transformed data. Did anybody ever consider this topic? Thank you, Bruno ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bruno L.

Hello, I am using logistic discriminant analysis to check whether a known classification Yobs can be predicted by few continuous variables X. What I do is to predict class probabilities with multinom() in nnet(), obtaining a predicted classification Ypred and then compute the percentage P(obs) of objects classified the same in Yobs and Ypred. My problem now is to figure out whether P(obs) is

Hello, I am writing down a general function to implement the bootstrapF method for repeated measures anova. I am passing the function several data frames: y = dependent subj = subject identifiers b = between-subjects factors (number = NB) w = within-subjects factors (number = NW) after grouping of all these variables in a single data frame the aov() call looks like this:

It would be great to know if and where an R code for Common Principal Component Analysis is available.

Dear list, is anybody aware of R implementations of the overlapping clustering methods by Arabie and Carroll (ADCLUS, MAPCLUS and INDCLUS)? I found around only their Fortran implementation of the MAPCLUS model, which comes practically without any documentation. Alternatively, has anybody used this Fortran program, and is willing to share some knowledge about its use? Thank you, Bruno

Working on Windows I have had to deal with CSV files that, unfortunately, contain embedded Control-Zs, i.e. ASCII character 26 in decimal, and the readLines() function in R on Windows (2.15.2 and 3.0.0) appears to truncate at the control-Z. There is no problem at all on Ubuntu Linux with R 3.0.0. Am I mistaken or is this genuine? # Create a small file with embedded Control-Z h3 <-

Hello, I am trying to obtain the partial r-square values (r^2 or R2) for individual predictors of an outcome variable in multiple linear regression. I am using the 'lm' function to calculate the beta coefficients, however, I would like to know the individual % contributions of several indepenent variables. I tried searching for this function in many R packages, but it has proven elusive

Hi, I am trying to write a function to automate multiple graph generation. My data looks like: Table of numeric values with the following headers: timeM1 statusM1 xM1 timeM2 statusM2 xM2 timeM3 statusM3 xM3 1 2 3 4 5 6 Where M1,M2, M3 hve no similarity except they have a max string length of 7. Examples are mcw0045, adl0003, lei0101. Now, what I want to do is Function(M1, M2,

Hi, I'm having some trouble with a bit of combined C & R code. I'm trying to write a C function to handle the for loops in a function I'm working on to calculate a similarity matrix. Jari Oksanen has kindly added the necessary changes to the vegan package so that I can use the vegdist function, so this isn't absolutely necessary. However, I'm stubborn and want to know

Hello, I'm afraid this message is going to be a little long (188 lines, not counting the headers). It is comprised, in fact, of two posts I sent to the comp.protocols.smb newsgroup, from which I've not received any replies. I'm hoping I can have better luck with the mailing list, (to which I've just subscribed, so it's probably most appropriate to send replies there...)

Hello: Forgive me, this is surely a simple question but I can't figure it out, having consulted the help archives and "Data Manipulation With R" (Spector). I have a list of 11 data frames with one common variable in each (prov). I'd like to use lapply to go through and recode one particular level of that common variable. I can get the recode to work, but it only returns the
