Hi there, I have had a problem with loading the package XLConnectJars_0.2-0.zip from the CRAN mirrors. The problem occurs when executing utils:::menuInstallPkgs() I have traced the problem down to the "download" internal command. It appears that files over approx 15 MB are being truncated. The exact point of truncation varies slightly but the truncation is on a 4096-byte boundary.
I am running => R version 2.15.1 (2012-06-22) -- "Roasted Marshmallows" Copyright (C) 2012 The R Foundation for Statistical Computing ISBN 3-900051-07-0 Platform: i386-pc-mingw32/i386 (32-bit) I have also run the code using the -- vanilla start-up parameter with no change in outcome. I am using "internet2" to get past our proxy server. I have isolated the problem using the following script derived from a code fragment called by the menuInstallPkgs() function. options(timeout = 120) makes no difference because the failure occurs before the timeout of 60 (or 120) seconds elapses. ## sample R code sequence to reproduce error setInternet2(TRUE); url <- "http://cran.csiro.au/bin/windows/contrib/2.15/"; dir <- "U:\\"; ## This download being reasonable small works OK file <- "XLConnect_0.2-1.zip"; status <- .Internal(download(paste0(url, file), paste0(dir, file), quiet=FALSE, mode="wb", cacheOK=FALSE)); cat(paste("the value of status for", file, "is", status, "\n\n")); ## This big download fails - a progress indicator quickly progresses to 99% and stops file <- "XLConnectJars_0.2-0.zip"; status <- .Internal(download(paste0(url, file), paste0(dir, file), quiet=FALSE, mode="wb", cacheOK=FALSE)); cat(paste("the value of status for", file, "is", status, "\n\n")); This produces the following output - trying URL 'http://cran.csiro.au/bin/windows/contrib/2.15/XLConnect_0.2-1.zip' Content type 'application/zip' length 1358587 bytes (1.3 Mb) opened URL downloaded 1.3 Mb the value of status for XLConnect_0.2-1.zip is 0 trying URL 'http://cran.csiro.au/bin/windows/contrib/2.15/XLConnectJars_0.2-0.zip' Content type 'application/zip' length 16486857 bytes (15.7 Mb) opened URL downloaded 15.6 Mb the value of status for XLConnectJars_0.2-0.zip is 0 Warning message: In eval(expr, envir, enclos) : downloaded length 16355328 != reported length 16486857 > Any suggestions on what is needed to get this going?
