Hi! I am new to looping and R in general; and I have sent waaaay to much time on this one problem and am about a hair away from doing it manually for the next two days. So, there is a package that while calculating the statistic creates lists (that look like matrices) in the background. Each item (there are 10 items) has one of these ‘matrix looking list’ that I need to extract data from. The

Hi, I was wondering if anyone could give me advice regarding using the lmer command in lme4 package to do logistic regression (mixed effects model). I use the following command lmer(ISH ~ArrayPathology2, random=~1|PatientID, data=HSDB4.noNA, family="binomial") where ISH is outcome(0 or 1), ArrayPathology2 is the variable of interest(factor), PatientID is random effect(factor), and

Hi the list, I am writing a package in S4 and I do not manage to understand a bug. The "R CMD check" and the "R CMD build" both work. Here is links to the package (not on CRAN yet for the raison that I explain bellow): http://christophe.genolini.free.fr/aTelecharger/kml_0.5.zip http://christophe.genolini.free.fr/aTelecharger/kml_0.5.tar.gz Then I install the package and I

This message is for those familiar with the survey package. I need to fit a weighted Cox model to accommodate the sampling weights as I have a case-control study with controls sampled at random from a database in a ratio 2:1 to cases (whom were all sampled). I want to make sure I am using the right svydesign syntax to specify this sampling design. Can anyone please check if the statement below is

Hi, I have a fairly simple repeated measures-type data set I've been attempting to analyze using the lme function in the nlme package. Repeated searches here and other places lead me to believe I have specified my model correctly. However, I am having trouble with post-hoc tests. From what I gather, other people are successfully using the glht function from the multcomp package to

Short: get rid of the loops I use and optimize runtime Dear all, I want to calculate for each row the amount of the month ago.

Hi there, I am trying to run a liner regression using lm with na.action = NULL, but I am getting an error message. Any ideas as to why this may be happening? Please see code and error message below: > reg_test<-lm(yy~.,data=test,na.action=NULL) Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : NA/NaN/Inf in foreign function call (arg 4) This message and

# BUG 1: returns empty vector if no NAs present > nona <- 1:10 > na.omit(nona) numeric(0) na.omit.default() has two lines where object[-omit] is used, where omit represents positions of NAs and thus without NAs omit = numeric(0) and since -numeric(0) = numeric(0) object[-omit] = numeric(0) It looks like an earlier version of na.omit.default had 'omit' defined as

Hi, I have a dataframe with 14319rows and 9 colums. for some rows there are null values.I want a dataframe without these null values.I wanna select only those that have values !=NA. kindly let me know how to do that.

I would link to know if with the nona howto I could fix that . I have been tried with no success to redirect that connection only to one link but its look like do not work . Here my configuration :

I don?t know if this question properly belongs on this list, but I?ll ask it here because I?ve been using R to run linear regression models, and it is only in using R (after switching from using SPSS) that I have discovered the process of fitting a linear model. However, after reading Crowley (2002), Fox (2002), Verzani (2004), Dalgaard (2002) and of course searching the R-help archives I cannot
