According to R-exts: The second purpose for @file{install.R} is to hold code that needs to be executed each time the package is attached, after the image is loaded. Few packages have a need for such code so @file{install.R} is normally an empty file. The optional file @file{R_PROFILE.R} is executed before the code in the @file{R} subdirectory and should be used to set up an

Hi, I'm not sure if this question has been answered before, but when I execute command "Rcmd INSTALL --build nws" to build an R package on Windows, the build process got stucked on the save image step. Here is the snapshot of the build process, --- Making package nws ---- adding build stamp to DESCRIPTION installing NAMESPACE file and metadata installing R files

Dear R-devel, There seems to be a bug in the Startup section, regarding the R_PROFILE environment variable in Windows. If not a bug in the Startup itself, perhaps a bug in the documentation. According to ?Startup: Then R searches for the site-wide startup profile unless the command line option '--no-site-file' was given. The name of this file is

I am running R 2.8.1 on SUSE Linux. I would like to be able to set R_PROFILE to two different possibilities. One when R is called by R CMD BATCH and another any other time. Is this possible? Mark Lyman, Statistician Engineering Systems & Integration, ATK

In R-devel, the Depends: field in the DESCRIPTION file is now used by library() to load the named packages before the current package, and also to set up the environment to save images and prepare for lazy loading. Would authors please use a minimally necessary set of packages in Depends, and put others in Suggests: -- the distinction is made in `Writing R Extensions'. On the other hand,

Hi I Can't connect to the Oracle database, any tips?

Dear Lister, I work with R 2.0.1 and Windows XP, and meet a strange trouble trying to make a R package with a make-package.bat file John Fox has kindly provided (see detailed script below). I am working with it since some months with excellent results (I do'nt use compiled C code so far). Just adding a new function in the R directory today, when running make-package and thus excuting

Hi all, Bioconductor has several metaData packages that contain quite large data sets. In the past, these data were simply held in the /data directory of the package as .rda files and load()ed as needed. Converting to using lazy data loading may have memory and performance advantages, but for the larger metaData packages the installation is painfully slow (it has taken > 30 min to install a

When I do a R CMD build --binary then I get the messages at the end of this post unless I specify LazyLoad: no in the DESCRIPRION file. If I do that then everything proceeds smoothly. R CMD check proceeds smoothly in either case. Is there something I should be aware of that is causing this message when I do not turn off lazy loading? I am using Windows XP and R 2.0.1 beta

Hola! I got past the problems I asked about two days ago, thanks. No I am updating CRAN package asypow (the daily package check on CRAN gave warnings due to .Rd problems, fixed). Now it PASSED Rcmd check (WindowsXP home edition, rw2000dev, on a new toshiba laptop, if that matters.) but then Rcmd build --binary gives problems: . . . preparing package asypow for lazy loading Error in

Hello at all ! What is the correct form to give a list form R (e.g. list(c(-1,1), "TestFile") ) to C. I have no problems, if I don't use character and I have also no problems to give a character vector form R to C. But, if I combine real and strings in a list then I don't know the correct syntax. I try it with following (an example): SEXP writeFile(SEXP headerR){ Image

Full_Name: Lars Hansen Version: 2.8.0 OS: Windows XP Pro x64 SP2 Submission from: (NULL) (71.39.177.36) Hi, I have run into a problem using "R CMD INSTALL" with the "--with-package-versions" option under Windows. It is a bit obscure, which could explain why other people have not run into it. We happen to have two packages with almost the same name. One name is a subset of

Hi, On Windows, package files in the inst/ subdir are installed after the lazyload creation. This differs from Linux where inst/ is installed _before_ lazyload creation. Since packages may need data in inst, I think the order on Windows should be changed. Perhaps like this: diff --git a/src/gnuwin32/MakePkg b/src/gnuwin32/MakePkg index 57af321..868e8f1 100644 --- a/src/gnuwin32/MakePkg +++

Hello, I am trying to compile packages for R2.0.0 patch in a win XP machine. Most of the packages compile without problems, with C or FTG or only R.

I'm trying to sort out some best practices for package development and understand some behavior of R CMD check that has me confused. Best practice question: If a package foo appears in the Depends field in the DESCRIPTION file of mypkg, should I refrain from using require(foo) in the R source files of mypkg? The Writing R Extensions manual says this about the Depends field: ... the

Hi, After some reading and experimentation I found that I cannot solve this problem: 1. I am starting R and check: > system("pwd") /home/woodstock/hoffmacw/R/test > system("echo $HOME") /home/woodstock/hoffmacw > system("echo $R_PROFILE") /home/woodstock/hoffmacw/R > system("ls $R_PROFILE/.Rprofile") /home/woodstock/hoffmacw/R/.Rprofile

The report on R_help about problems loading package irr (in a UTF-8 locale, it seemed) prompted me to look a little deeper. There are quite a few packages with Latin-1 chars in their .R files, and a couple in UTF-8. Apart from non-ASCII chars in comments, this is a problem as the code concerned cannot be represented in some locales R runs in (for example Japanese on Windows). It happens

In DESCRIPTION if I set LazyLoad to 'yes' will data.table (for example) then be byte compiled for users who install the binary package from CRAN on Windows? This question is based on reading section 1.2 of this document : http://www.divms.uiowa.edu/~luke/R/compiler/compiler.pdf I've searched r-devel and Stack Overflow history and have found questions and answers relating to R CMD
