Hi, is it possible to have non-Sweave vignettes(*) in inst/doc/ be listed under 'Downloads' on CRAN package pages? For instance, in my R.rsp package I have a inst/doc/report.pdf (part of the source *.tar.gz) that is not detected/listed. The PDF is not based on a Sweave vignette but an *.tex.rsp vignette that is dynamically created via inst/doc/Makefile. It is listed (*) BTW, can the

Hi, I would like to suggest a standard where all packages provide an Rd page with the same name (or aliased) as the name of package so that help(<package name>) or ?<package name> is always here. This especially of interest to large packages with a large package index. This page could explain the package in general and gives some hints on how to start - not like extensive

Hi, in R CMD check, the version of the package being checked is reported, e.g. Thu Sep 9 05:02:30 2010: Checking package R.utils (SVN revision 399) ... * using log directory ?/srv/R/R.check/R-devel/PKGS/R.utils.Rcheck? * using R version 2.12.0 Under development (unstable) (2010-09-07 r52876) * using platform: x86_64-unknown-linux-gnu (64-bit) * using session charset: UTF-8 * checking for file

R-core, may I suggest that the error message returns the absolute path (or even the relative path) and not just the filename/basename, e.g. "Fatal error: unable to restore saved data in C:/Users/foo/.RData" /Henrik On Thu, Sep 18, 2008 at 6:41 AM, Green, Paul <pgreen at umich.edu> wrote: > We are using R in our class.

Hi, when doing as.double() on an object that is already a double, the object seems to be copied internally, doubling the memory requirement. See example below. Same for as.character() etc. Is this intended? Example: % R --vanilla > x <- double(1e7) > gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 234019 6.3 467875 12.5 350000 9.4 Vcells 10103774 77.1

In the 'parallel' package there is detectCores(), which tries its best to infer the number of cores on the current machine. This is useful if you wish to utilize the *maximum* number of cores on the machine. Several are using this to set the number of cores when parallelizing, sometimes also hardcoded within 3rd-party scripts/package code, but there are several settings where you wish to

ISSUE: Using *forks* for parallel processing in R is not always safe. The `parallel::mclapply()` function uses forked processes to parallelize. One example where it has been confirmed that forked processing causes problems is when running R via RStudio. It is recommended to use PSOCK clusters (`parallel::makeCluster()`) rather than *forked* processes when running R from RStudio (

ISSUE: On MS Windows, running cmd.exe, calling Rscript --vanilla -e "port <- tools::startDynamicHelp(); port; port <- tools::startDynamicHelp(FALSE); port" will sometimes stall R at the end, preventing it from existing. This also happens when running R in interactive mode. It seems to stem from calling tools::startDynamicHelp(FALSE). Before filing a formal bug report, can

(Bcc: CRAN) This is a proposal helping CRAN and alike as well as individual developers to avoid stray R processes being left behind that might be produced when an example or a package test fails to set up a parallel::makeCluster(). ISSUE If a package test sets up a PSOCK cluster and then the master process dies for one reason or the other, the PSOCK worker processes will remain running for 30

Hi, is it possible to add a custom script such that it is called via R CMD <custom>? Is R CMD searching for it elsewhere than R_HOME/bin/? I'm looking for an non-admin alternative, so copying the script to R_HOME/bin/ will not do (in case the user don't have enough permission to write there). /Henrik

I'd like to suggest that whenever there is no S3 method implementation available for a particular class, that the error message would also report the class structure of the object dispatched on. Example: foo <- function(...) UseMethod("foo") foo.ClassA <- function(object, ...) { cat("foo() for ClassA called.\n") } > foo(structure(1, class="ClassA"))

Hi, sessionInfo() has been proven really useful, but you still often have to ask for additional information in order to help troubleshooting. For instance, for troubleshooting the aroma.affymetrix, it is very helpful to know what the current working directory is, for other packages certain system environment variables might be useful and so on. One solution could be to provide support for hook

Hi, I keep seeing the problem where people are download binary files as text (mode="w") when using R's download.file() for FTP/HTTP downloads. It often results in unnecessary troubleshooting until one concludes that the downloaded file has been corrupted due to (what I think is) translated newlines. Search the r-help mailing list and you'll find other examples of this. This

Full_Name: Henrik Bengtsson Version: 1.3.1 OS: WinMe Submission from: (NULL) (130.235.2.229) I found the following bug on WinMe (I call it a bug, since the behavior is different on WinMe than for instance Sun Solaris): When calling file.exists() with an existing directory name ending with a "/" (slash) [R] on WinMe will return FALSE, but when doing the same without the ending

Hi, is it possible to update the modification time stamp of a file using R (on file systems supporting it)? It is sufficient to update the modification time to the current time. The best I can do for now is: touchFile <- function(pathname, ...) { if (!file.exists(pathname)) stop("No such file: ", pathname); info <- file.info(pathname); if (info$isdir)

Hi, I am not sure if this is a bug or a non-implement feature of text-drawing functions with TeX-style expression, but hat() and some of its equals does not get the right "bounding boxes" if they are put in sub- or superscripts. For instance, for the expression 'b[hat(a)]' the hat() seems to shift 'hat(a)' too much to the right of 'b'. Try the below example and

Full_Name: Henrik Bengtsson Version: 1.3.0 OS: Windows Me Submission from: (NULL) (216.175.122.171) I realized that the title of packages in the library index when they are in a bundle is the title of the bundle and not the package. It looks like the TITLE file, which apparently is used for generating the library index, takes the value of the bundle's title and not the package's title.

Hi, for 'affxparser' (Bioconductor), we needed a function to test if a certain package was loaded or not, but we did not want to load it if it wasn't, which is why we couldn't use require(). We came up with the following solution: isPackageLoaded <- function(package, version=NULL, ...) { s <- search(); if (is.null(version)) { s <-
