...sly, by changing the line mentioned above? Thank you for your help, Katharina PS: I am working with R 2.0.0 PPS: Concrete error message: "Error in model.frame.default(Terms, newdata, na.action = na.action, xlev = object$xlevels) : factor I(kanton) has new level(s) GE" -- K.

...soon as I want to predict the response variable a, I get the following error message: "Error in model.frame.default(Terms, newdata, na.action = na.action, xlev = object$xlevels) : factor d has new level(s) q" Does anybody have a solution to this problem? Thank you in advance, K. Steinmann (working with R 2.0.0) Code: library(MASS) a <- rnbinom(200, 1, 0.5) b <- (1:200) c <- (30:229) d <- rep(c("q", "r", "s", "t"), rep(50,4)) data_frame <- data.frame(a,b,c,d) model_1 = glm.nb(a ~ b + d , data = data_frame) pred_model_1...

Question: How can I get access to the bias value of a boot statistic? Details: Boot function: boot(data, statistic, R, sim="ordinary", stype="i", strata=rep(1,n), L=NULL, m=0, weights=NULL, ran.gen=function(d, p) d, mle=NULL, ...) When I create an object, containing the bootstrap statistic (object <- boot (....))I can call it and will get an output

...discriminate the groups is used by "lda" (Fisher's linar discriminant function, diagonal linear discriminant analysis, likelihood ratio discriminant rule, ...)? 2. How can I see, which method is used? (Typing just lda does not give me any code). Thank you in advance Best wishes K. Steinmann

...es ldap passwd sync = yes ldap suffix = ou=Samba,dc=alvhaus,dc=ch ldap ssl = no ldap user suffix = ou=People For me it looks right! And it's also working, if People and Group aren't aliased. So I guess samba pdc is not resolving aliases. Version 3.4.0 -Ivo Steinmann

Dear R-helpers, Using the package Lattice, I performed a PCA. For example pca.summary <- summary(pc.cr <- princomp(USArrests, cor = TRUE)) The Output of "pca.summary" looks as follows: Importance of components: Comp.1 Comp.2 Comp.3 Comp.4 Standard deviation 1.5748783 0.9948694 0.5971291 0.41644938 Proportion of Variance 0.6200604

Dear R-mailers, I would like to test for equality of population covariance matrices. But I can't find a R tool to do so. I saw, that other people had the same question, but I could not find an answer to it, I would appreciate to know the missed link. Thank you, b.w. K. Steinmann

Support for SLES9 seems to be pretty much lacking at the moment. The OCFS2 site [1] states OCFS2 is supported with SP2+. There actually does not exist a SP2+ for SLES9 (or should this rather read "will be supported in SP3" instead?). Latest RPMs that come with SLES9 SP2 are 0.99.14 which has critical known bugs and is unusable. Anybody got to compile current source on SLES9 x86_64?
