Hi all. I'm reading in a flat, comma-delimited flat file using read.csv. It works marvelously for the most part. I am using the colClasses argument to, basically, create numeric, factor and character classes for the columns I'm reading in. However, a couple of the fields in the file are date fields. I'm fully aware that POSIXct can be used as a class, however the field must obey,

I just upgraded to 2.10.1 on a WinXPSP2 machine. When I type help.start() R attempts to open a browser session at http://127.0.0.1:27594/doc/html/index.html using my default browser (Firefox 3.6) and is unable to connect. If I then open the same page using IE 8, it works just fine. How do I fix/change R so that it works with Firefox? Thanks Bill William J. Raynor, Jr. Ph.D. Technical Leader III

the study design of the data I have to analyse is simple. There is 1 control group (CTRL) and 2 different treatment groups (TREAT_1 and TREAT_2). The data also includes 2 covariates COV1 and COV2. I have been asked to check if there is a linear or quadratic treatment effect in the data. I created a dummy data set to explain my situation: df1 <- data.frame( Observation =

Hello R-helpers. We have a question about AIC values. We ran several different GLMs (quadratic, interactions) and our lowest AIC values were the same for several different models.

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
