Good afternoon Using R 2.9.2 on a machine running Windows XP I have a longitudinal data set, with data on schools and their test scores over a four year period. I have centered year, and run the following m1.mod1 <- lme(fixed = math_1 ~ I(year-2007.5)*TFC_, data = long, random = ~I(year-2007.5)|schoolnum, na.action = "na.omit") where

Good morning I am learning about NLME and LME4, using Pinheiro and Bates and other materials from Douglas Bates, but I have not seen anything on how to do variable selection sensibly in this type of model. In OLS regression, I frequently use the lasso, but googling did not reveal a method for lasso with mixed models. Most of the material I've seen on these packages is about models with very

Hi the list, I write a package for clusterizing longitudinal data using a non parametric algorithm. I develop the package under windows. To be as user friendly as possible, the package use some graphical procedure to "show" to the user the evolution of the cluster construction, and to export the graph in a friendly way. Here are some example : http://christophe.genolini.free.fr/kml

KmL, version 0.9.2 KmL is a new implematation of k-means for longitudinal data (or trajectories). This algorithm is able to deal with missing value and provides an easy way to re roll the algorithm several times, varying the starting conditions and/or the number of clusters looked for. It also provide a graphical interface to let the user chose the best clusterization, when classical

Hello Running R2.9.2 on Windows XP I am puzzled by the performance of LME in situations where there are missing data. As I understand it, one of the strengths of this sort of model is how well it deals with missing data, yet lme requires nonmissing data. Thus, m1.mod1 <- lme(fixed = math_1 ~ I(year-2007.5)*TFC_, data = long, random =

Good afternoon Running R2.10.0 on Windows I have a data frame that includes (among much else) a factor (In_2006) and a continuous variable (math_3_4). I would like to find the 2 cases for In_2006 = 0 that are closest to each case where In_2006 = 1. My data looks like In_2006 math_3_4 0 55.1 1 51.6 1 18.1 1 26.6 1 14.1

Good morning I just got a new computer with Windows 7. R works fine, but the editor I am used to using "RWinEdt" does not. I did find one blog post on how to get RWinEdt to work in Windows 7, but I could not get those instructions to work either. Is there a patch for RWinEdt? If not, is there another good R editor that works under Windows 7? I tried RSiteSearch with various

Hi the list, I am a member of the organizing comity of the French Statistics Association (SFdS)'s conference. We are looking for sponsors. Some software (SAS, RITME, ...) are represented. Do you know if there is any possibility to be sponsored by R (or by an association close to R)? Do you think I can ask to the R fondation? Sincerely Christophe -- Christophe Genolini Maître de

Hi I can install RWinEdt if I start R with administrator rigths, but it does not paste my code to the console. I found advice in the link below how to manage the problem, but it did not work, any other idea? http://yusung.blogspot.com/2009/01/rwinedt-and-windows-vistawindow-7.html Thanks a lot,Johannes >From: Uwe Ligges <ligges_at_statistik.tu-dortmund.de> >Date: Sun, 08 Nov 2009

Hi Michael, with res.uc$conf you'll get the single configurations for each rater. You can use these to produce the plot you want to have.

Good morning I recently shifted to digest mode; I get the digest each day (sometimes two in a day) and when I open the first file it opens as a text file with a list of topics; but then it is hard to find the right message. In a list of 100 or so links, counting to find link number 53 or whatever is painstaking and prone to error. How do people find the right messages? Thanks Peter Peter L.

Hi   I am using following code to produce a xyplot for some longitudinal data. There are 2 panels. It produced all longitudinal trajectories with mean profile. But since the dataset it very large plot looks very messy. I want to show, say 10 randomly selected individual longitudinal trajectories together with mean profile for entire dataset. Could any help me to alter the following code to do

Hi the list, I have some basic questions about "writing a package". On which list shall I post them? Theoretically, I am supposed to post them on r-devel, but all the questions on this list are very advance questions, not basic ones... So I don't know what to do.
