Hi all, I am trying to download, decompress and read a csv file. My code: myurl <- "ftp://ftp.ncbi.nih.gov/pub/geo/DATA/supplementary/series/GSE24729/GSE24729_MitoNuclear_suppl_male_stats.csv.gz" # myfile <- "GSE24729_MitoNuclear_suppl_male_stats.csv.gz" # download.file(myurl, destfile=myfile, mode="w") # mycon <- gzcon(gzfile(myfile,

To me it seems like writeBin() writes one char/byte more than expected. > con <- file("testbin", "wb") > writeBin("ttccggaa", con) > close(con) > con <- file("testbin", "rb") > readBin(con, what="character") [1] "ttccggaa" > seek(con, what=NA) [1] 9 > close(con) > con <-

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'm using R-2.12 on a linux 64bit machine. When I run a chunk of code inside a foreach() %do% { ...} or %dopar% {...} (with doMC backend) I keep getting a segfault. Running the *same* code within lapply(something, function(x) ... ) doesn't result in any segfaults. I'll paste the output below, but I'm not sure it would be helpful. I'm more curious how to go about smoking

Dear all, for a CRAN-package that depends on another Bioconductor-package I find two things annoying and would like to know whether there are some workarounds: 1) Is there some inevitable problem that install.packages does not install uninstalled packages (on which the specified package depends) also from Bioconductor (in the correct version)? 2) In my understanding (please correct me if
