I have a data set for different time intervals. The data has three comment lines before data for each time interval. For each time interval there are 500 data points. I want to change the dataset such that I have the following format: t1 t2 t3 ................ 0.00208 0.00417 0.00625 ................. a1 a2 a3 ...................

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 =

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

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. We don't know how to interpret this. Any thoughts? Thanks in advance. Katrina Shelding _________________________________________________________________ e. [[alternative HTML version deleted]]

Hi, I need to calculate the average length of a trait per individual. I am not used to working with R so I could use some help.

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
