...ubject indicator" variable (called "id") three dependent variables (varD, varE, var F) three independent variables (varA, varB, varC) I want to fit 9 lme models, one per posible combination (DA, DB, DC, EA, EB, EC, FA, FB, FC). In stead of writting the 9 lme models, I want to do it sistematically (the example is a simplification of what I really have). Here you have the comands for the first model: library(nlme) set.seed(50) a<-data.frame(array(c(rep(1:10,10), rnorm(600)), c(100,7))) names(a)<-c("id", "varA", "varB", "varC", "varD",...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've got a serious problem with my samba installation (samba 3.0.2.a, compiled from sources). The problem seems to occour when printing a file on a printer connected ~ to our samba server. Other printers on the same server seems to work just fine. Note that the thing is not sistematic... some days it occours many times, and other days all

Hello! I don't know if there is some R-package able to associate ontology to a long list of GeneBank Name (a txt-tab file or an XML file), i.e. I would as output a formatted file with 4 columns (1:GeneBank Name 2,3,4:ontology). I know that I have to perform a mapping of genes, I got a look on AnnBuilder pkg, but I 've not idea from where to start. Some suggestion? Thanks in advance!

Hi all, I am new to R. I made this script that plots the deviation of a skellam-distributed random variable with respect to the skellam distribution. I would expect to get random errors, but the plot sistematically shows a non-random pattern (first a peak and then a low). I don't know how to explain this. Can somebody enlighten me?? require(skellam) n <- 5000 lam1 <- 5.45 lam2 <- 2.78 p1 <- rpois(n, lam1) p2 <- rpois(n, lam2) rho <- cor(p1,p2) z <- hist(p1-p2, plot=FALSE) mu1 &l...
