Dear WizaRds! A trivial question indeed on selecting subsets in data frames. I am sorry. Unfortunately, I did not find any helpful information on the introduction, searched the help archive and read in introductory books. Please help: I want to select column "KB" which is read via read.csv2 as a data.frame into d. I checked that it is indeed a data.frame object and included the

Let me preface my question by stressing that I am much less interested in the answer than in learning a way I could have *found the answer myself*. (As helpful as the participants in this list are, I have far too many R-related questions to resolve by posting here, and as I've written before, in my experience the R documentation has not been very helpful, but I remain hopeful that I may have

Hello everybody, I frequently have to produce barplots from variables the natural variation of which is far away from zero. A typical range would be, say from -16 to -28. So, the following example should give an "honest" presentation: x<-c(-20,-22,-21,-28) barplot(x,beside=T,ylim=c(-18,-30)) But using anything else but "0" for the first element of ylim leads to strange

Dear R Helpers, I have a list that contains a number of objects, each of them financial statement data from quantmod (although I don't think that knowledge of quantmod is necessary to help with this problem). > str(listfinobj) chr [1:4815] "A.f" "AA.f" "AACC.f" "AAME.f" "AAN.f" "AAON.f" "AAP.f" "AAPL.f"

I own a lot to the folks on r-help list, especially arun who answered every of my question and was never wrong. I am disinclined to once again ask this question, since it is more arithmatic than technical. But, having worked 2 days on it, I realized my brain is just not juicy enough.... Here is the problem.

Dear r-help list members, Is there an R package to compute the power and sample size of generalized linear models with categorical independent variables? I am especially interested in the negative binomial error model. Failing this, is there any package outside of R that does this kind of calculation? Thanks!
