Dear R Community, I am currently facing this seemingly obscure Problem with Panel Corrected Standard Errors (PCSE) following Beck & Katz (1995). As the authors suggest, I regressed a linear model (tmodel) with lm() with option "na.action=na.exclude" (I have also tried other options here). My dataframe is organized in pooled times series fashion, but with various missing values

Hi, sorry if this has been asked before, but I just can't find anywhere on the net that tells me how to do this. I've been trying for ages to get this right, using various forms of --include-from, --exclude, --filter, etc. I want to copy only specific directories that contain specific filetypes, from sourcedir to destdir. For example, I want to copy all .mp3 and all .ogg files found in

Hi, I am running a learning experiment in which both training subjects and controls complete a pretest and posttest. All analyses are being conducted in R. We are looking to compare two training methodologies, and so have run this experiment twice, once with each methodology. Methodology is a between-subjects factor. Trying to run this analysis with every factor included (ie, subject as a

Hi, I''m new using RoR and I have a ... trouble with f.collection.select What I have in a table is ... for example group code GroupA 07A GroupA 08A GroupA 10B GroupB 06A GroupB 11B GroupB 07B GroupC 10A GroupC 09A GroupC 09B when I use <%= f.collection_select :grupo, Equipo.find(:all), :id, :name, prompt: ''Choose a Group'' %>

Greetings! I am a new user of R. The only one in my department, all others use SPSS. I have two data sets of students with test scores, pretest and posttest. The first column StuNum and then columns of scores. The problem is that the lists are slightly different not all students are in both data sets. So I did: intersect(pretest$StuNum, posttest$StuNum) -> common.id At this point I need

Just two clarifying questions about the package "pcse". Argument "groupN": It should be a factor that tells us to what subgroup each record belongs, right? Argument "groupT" should be a vector that contains the time identifier. Can it be just a factor (e.g., 1, 2, 3, etc.) - or does it have to be in the date format? Thank you very much! -- Dimitri Liakhovitski

Dear R users, I use the excelent Anova function of the library car because the easy way to get sphericity correction. Unless I use the scan function. I have not been able to access the values ​​of sum squares and degrees of freedom for each effect in the univariate summary table. Example of the car library for Anova function: library(car) phase <- factor(rep(c("pretest",

Hello there, I would like to produce a plot of x<-c(4,5,6),which is the mean of each group and y<-c('groupA','groupB','groupC'). plot (x,y) can not produce any graphics because y is not numerical. What should I do to produce this graphic? Thank you in advance Lisa Wang Princess Margaret Hospital Toronto,Ca

So I discovered yesterday that if puppet changes the gid of a group it doesn''t go through the file system and update them with the new correct gid (at least this was the case on RHEL5 and client puppet v2.6.16 and puppetmaster 2.7.12). Now I thought that it might be possible to have puppet execute something like find /home/ -group <old_gid> | xargs chgrp groupname. However

Hi, I am fairly new to R and still trying to figure out how it all works, and I have run into a few issues. I apologize in advance if my questions are a bit basic, I'm also no statistics wizard, so part of my problem my be a more fundamental lack of knowledge in the field. I have a dataset that looks something like this: Week Subj Group Readout 0 1 A 352.2 1 1 A

Hi, I'm looking for an easy way to discretize factors in R I've noticed that the lm function does this automatically with a nice result. If I have group <- c("A", "B","B","C","C","C") and run: lm(result ~ x1 + group) The lm function has split the group into separate binary variables {0,1} before performing the

Is there an easy way to make graphs for the following data. I have pretest and posttest scores for men and women. I would like to form a 'titlted segment' plot for the data. That is, make segments joining the scores, with different types of segments for men and women. Example data: menpre <- c(43,42,26,39,60,60,46) menpost <- c(40,41,36,42,54,58,43) womenpre <-

Dear list, I would like to run an ANCOVA using car::Anova with repeated measures factors, but I can't figure out how to do it. My (between-subjects) covariate always interacts with my within-subject factors. As far as I understand ANCOVA, covariates usually do not interact with the effects of interest but are simply additive (or am I wrong here?). More specifically, I can add a covariate as

Hello dear R members. I have been learning the Anova syntax in order to perform an SS type III Anova with repeated measures designs (thank you Prof. John Fox!) And another question came up: where/what are the (between/within) residuals for my model? ############ Play code: phase <- factor(rep(c("pretest", "posttest", "followup"), c(5, 5, 5)),
