...ge's functions requires this data frame. A toy example is: test<-function() { data(RutgersMapB36) return(RutgersMapB36[,1]) } R CMD check returns a NOTE: test: no visible binding for global variable 'RutgersMapB36' Is there any way to avoid this NOTE?

Hello to R people Does anybody know to calculate exact logistic regression in R? Does such option exist anywhere? Surprisingly, could not find it using search engine. It is hard to believe, however, that such useful function is not implemented in R yet? Could you help, please Thank you Denis

Dear all, I have some difficulty getting R-1.3.0 to run on the alpha, with osf4.0e (Tru64, or whatever they call it... :-) ). configure reports the following configuration: R is now configured for alphaev6-dec-osf4.0e Source directory: . Installation directory: /astro/local C compiler: gcc -mieee -g -O2 C++ compiler: c++ -g -O2 FORTRAN

In the iterative weighted least squares loop of the glm.fit function, a QR decomposition of the matrix X*sqrt(w) is obtained at each iteration, using fitted values of the mean response mu from the previous interation. Here "X" is the design matrix, w = wt*(d(mu)/d(eta))/variance(mu), "wt" is the vector of weights, and "d(mu)/d(eta)" is the derivative of mu wrt the

...gon, MD, DrPH -----old post 2002 end------------ At that time, the answers were not too encouraging. Anyway, I might have the very same query 2008. Ok, I tried to do some homework and started to look for packages maybe implementing different methods. I did run across 'elrm' (Zamar, D., McNeney, B. & Graham, J., 2007), but I am unsure whether this package is appropriate for my original 1:3 matched design. - ---Blah blah part end-------- - ---Questions, finally!--- So my questions to you are: 1) Is the problem I describe above likely related to small sample sizes? 2) Do you have ex...
