...he column (O-E)^2/V mean? What is V, and how does this possibly relate to the calculated Chisq? The syntax would be something like this: gr1<-c(1,2,3,4,5) gr <-rep(1,length(gr1)) gr2<-c(6,7,8,9) gr<-c(gr,rep(2,length(gr2))) surv<-c(gr1,gr2) event<-rep(1,7) event<-c(event,0,0) mydatafile<-cbind(surv,gr,event) mydatafile <- data.frame(mydatafile) mydatafile$gr<-factor(mydatafile$gr) library(survival) mydatafile.LR<-survdiff(Surv(surv,event)~gr,data=mydatafile) print(mydatafile.LR) And the response would be: Call: survdiff(formula = Surv(surv, event) ~ gr, data = myd...

...he parameters passed to an R script, but I don't know how to pass them. There is an option --args that should cut the rest of the line off the command line. The problem is however that BATCH syntax is: 'R CMD BATCH [options] inFile [outFile]', i.e. if I write 'R CMD BATCH --args myDataFile myScript.R' or 'R CMD BATCH --args myDataFile < myScript.R' (similar was posted on some R help under Windows) it is not going to work because then BATCH doesn't know about myScript.R - it is considered as a parameter, so only 'R CMD BATCH' is executed. If however I us...

...e data set, but I'd like the option of reading in the data column, and converting it to a vector that has all row values (comma seperated or not) each have their own vector entry, so that the "table(columnData)" function does counts correctly. So some code: myData = read.delim(myDataFile, row.names=1,header=TRUE,skip=10); #works fine myColumn = myData[[question]]; #works fine, selects correct question column data myColumn data is now e.g.: 1 0 2 0,2 0 3 2 2,1 with the comma seperated values looking like atomic string values I guess. But I w...

Hi, I have seen the answer to this sometime before but I just can't find it again - pointers appreciated. I have a package that contains some data.frames saved as .Rda files in the data/ directory. When the package is loaded I would like to have them be available in the workspace (without the user having to explicitly load them using data(...)). If my package does not use a NAMESPACE, I can

Hi, I am trying to parse XML files and read them into R as a data frame, but have been unable to find examples which I could apply successfully. I'm afraid I don't know much about XML, which makes this all the more difficult. If someone could point me in the right direction to a resource (preferably with an example or two), it would be greatly appreciated. Here is a snippet from one of

Hi all, I have some data x, which are actualy consisted of numerical enties. But the class of this matrix is set to be "factor" by someone else. I used "class(x)", it turns out to be "factor". So I can not calculate them. How can I turn them into numerical data so that I can apply math operations on them? Thanks a lot for your help. Selina [[alternative HTML
