Relatively new to R, I'm trying to do a relatively simple task. I have data set that has several variables arranged by SubjID and visit, with multiple observations for that combination. I do linear regression on those multiple observations, then generated a set of interpolated values from the regression at fixed intervals along "x". I now want to average each of those across all the

Dear all, I'm quite new in R and I have a problem with the function which. When I use it to select a subset of a dataframe it works well but somewhere R takes trace of the past dataframe and this creates problems with following operations. For example: sentences <- read.xls("frasi.tot.march.3.xls", header=TRUE) head(sentences) fam subjID Cond Code reg total first

Dear All, I met problems when doing contrast and now really need some help in the model below: Fit=gam(y~treat+SEQUENCE+PERIOD+SEX+s(x),data=dat, random=list(SUBJID=~1),correlation=corAR1(form=~1|SUBJID)) And error message keeps coming out when I want to compare the differences between treatments: Diff=contrast(Fit, list(treat=treatment[-placebo.pos]),list(treat="Placebo"),

Hi, I have a multilevel situation where subjects are nested within clinics, and each subject has multiple measurements. For simplicity, suppose there 4 clinics, 3 subjects per clinic, and each subject has 3 repeated measures. Outcome is continuous. I am trying to implement this model with lmer function in lme4 library.

This is very possibly not a question on R. I was under the impression that the argument that gives rise to Fisher's LSD method in ANOVA works in other situations with three-way comparisons too, given that formal logic works the same ("if the omnibus test rejects, only two of the three groups may be equal, and therefore only one hypothesis can be rejected falsely"). However, when I

This is a basics beginner question. I attempted fitting a a Poisson GLM to data that is non-integer ( I believe Poisson is suitable in this case, because it is modelling counts of infections, but the data collected are all non-negative numbers with 2 decimal places). My question is, since R doesn't return an error with this glm fitting, is it important that the data is non-integer. How does

Hi, I have many printers installed under cups on a samba server, so the printers can be used and installed on Mac and PCs. My problem appeared with some new printers I bought and their PPDs. Under Cups, all the PPD options (Page Sizes, Trays, etc..) appear if I looked at them from the cups printer configuration page or if I use it from a Mac. But if I install the printers under windows

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
