Dear All, reposting, because I did not find a solution, maybe someone could check the example below. It's taken from the help page of survdiff. Executing it, gives the error "Error in floor(temp) : Non-numeric argument to mathematical function" best regards, Heinz library(survival) ## Example from help page of survdiff ## Expected survival for heart transplant patients based

Hi, I seem to be facing a strange problem when I use Sweave for creating a LaTeX document of the R lme() output --- The EPS and PDF figure files get created, but are empty. I have attached a reproducible example below (taken from the R lme() help example). ------------------------------------------------------------------------------------ \documentclass[a4paper,10pt]{article}

Dear All, since years I am struggling with Surv objects in data.frames. The following seems to have to do with it. See below the modified example from the help page of survSplit. The original works, as expected. If, however, a Surv object is added to the data.frame, each record gets doubled. Is there some solution other than avoiding Surv objects in data.frames? Thanks, Heinz

Dear All, to drop unused factor levels two ways are outlined in R-help. In both cases a label attribute is lost. The same happens, when using car:::recode. Is there a simple way to avoid losing attributes? Thanks, Heinz ## example ff <- factor(substring("statistics", 1:10, 1:10), levels=letters) attributes(ff)$label <- 'test label' attributes(ff)$label gg <- ff[,

Dear Rxperts, Using R 2.8.1 and trying install.views("Cluster") getting error Error: could not find function "install.views" Please help:-( -- Oscar Oscar A. Linares Molecular Medicine Unit Bolles Harbor Monroe, Michigan [[alternative HTML version deleted]]

I have found Sweave() to be great for producing PDF documents. I have been experimenting with RweaveHTML (from the R2HTML) package and have had moderate success. My main issue has been that I simply want the R output to be shown verbatim in the HTML document but RweaveHTML tends to convert most output to a table, for example. So, is there a way to force the RweaveHTML driver to simply provide

Hi all, I believe there is an issue with passing NULL to the function I(). class(NULL) # "NULL" (as expected) print(NULL) # NULL (as expected) is.null(NULL) # TRUE (as expected) According to the documentation I() should return a copy of its input with class "AsIs" preprended: class(I(NULL)) # "AsIs" (as expected) print(I(NULL)) # list() (not expected!

Well, I've asked a couple times already but I will ask one more, since I still havent' managed to get any further. We have several sites. Each site has it's own network and domain. We are connected via a WAN. Is the best practice to have one WINS server for each site? Or is a single WINS server for the WAN the way to go? Right now I have a single WINS server for the WAN. I CAN NOT

Hi all, The documentation for head() and tail() describes the behavior of these generic functions when n is strictly positive (n > 0) and strictly negative (n < 0). How these functions work when given a zero value is not defined. Both GNU command-line utilities head and tail behave differently with +0 and -0: http://man7.org/linux/man-pages/man1/head.1.html

In addition, signed zeroes only exist for floating point numbers - the bit patterns for as.integer(0) and as.integer(-0) are identical.

I've got a question regarding Cisco IP Phones and licencing. When using a third party PBX like asterisk is a licence required for the Cisco phones ? Has anyone got anything in writing from Cisco to clarify this ? Eg can I just use CP-7961G or do I need CP-7961G-CH1 even though I'm not using Cisco Callmanager ? HYPERLINK

Dear R developers, I have a new class, which I called "Molecule", and have tried to define = a "+" operation for 2 objects of this class.
