similar to: Auto-upgrading a package under Windows ?

Hello, I have a package with a namespace. Because I use Roxygen that overwrites the NAMESPACE file each time it is run, I use a R/zzz.R file with an .onLoad() and .onUnload() functions to take care of loading and unloading my shared library. The problem: if I load my library from a local directory, then the unloading of the package fails, e.g: # loads fine >library(Foo,

If one wants to unload compiled code for a package containing a namespace, my understanding is that .onUnload() should be used, with a call to library.dynam.unload(). This is used in e.g., the stats and methods packages, but it appears to me that the compiled code is not being unloaded when the package is detached(). Am I misunderstanding something? Best, Jim > search() [1]

I have a package that I'm developing that I need to unload the library. Long story short I figured out that the leaving the compiled code loaded lead to a segmentation fault, but unloading the code will fix it. I've read the documentation and it appears that there are several ways to do this? What is the popper accepted current standard for unloading compiled code? The options as I

Hi, it seems that the package hooks .onLoad and its C++ pendant R_unload_mylib are actually not called when R quits, but only when explicitly calling detach('package:mylib', unload = TRUE). Maybe this is platform specific, I'm on Ubuntu 13.10 - R 3.0.2 (see below). * is there a mechanism that a package can use to effectively do some cleanup on standard exit, such as calling

I've noticed that many of the "base" R packages have an .onUnload() function which automatically unloads compiled shared libraries with library.dynam.unload(). For example: > stats:::.onUnload function (libpath) library.dynam.unload("stats", libpath) <bytecode: 0x1033b9c30> <environment: namespace:stats> I've noticed that many other packages don't

The survival package has a firstlib.R file that I had forgotton and just reviewed. After deleting several bits which had a use 10 years ago during my Splus to R transition, the only thing remaining is .onUnload <- function(libpath) library.dynam.unload("survival", libpath) Does this bit of code still serve a purpose? Can I toss it? Terry T.

I have a question about antialiasing when R generates bitmaps. (This follows a thread on the ggplot2 mailing list.) I mostly use R on Linux, although I sometimes use it in Mac and Windows as well. On Linux, I've found that plotting shapes 15-18 via cairo results in bad-looking output. The points are not antialiased, and they are jagged and misshapen. Plots generated in Windows also aren't

I just found out that an .onLoad() function such as this stylized one (where I just renamed some identifiers) .onLoad <- function(lib, pkg) { require(zoo, quiet=TRUE, warn.conflicts=FALSE) library.dynam("foolib", pkg, lib ) if (.Platform$OS.type != "windows") { initSomeServices() } if (.Platform$OS.type != "windows") {

Hi, I am wondering if there is a parameter in library() so that it can reinforce package to be reloaded. It helps when you test your modified package by yourself. Otherwise, my way is to re-start Rgui. (by reading ?library, I understand this option is not implemented) "...Both functions check and update the list of currently loaded packages and do not reload a package which is already

Hola! There is a nuisance that the number of directories with name starting Rtmp (and always empty) in my temp directory is increasing over time. I put the following in my .Rprofile: tmp0001 <- tempdir() setHook( packageEvent("base","onUnload"), function(...) unlink( tmp0001, recursive=TRUE) ) which solves part of the problem, but not all. So there are also

Hello, I am unable to start an R session by double-clicking on an existing .RData file from the Windoze file explorer. A dialogue appears with the message "Fatal error: unable to restore saved data in .RData", and I notice in the R Console the last few lines are: "Loading required package: R2HTML NULL error in function () : unused argument(s) (1:43)" I tried starting

Thanks for all your great answers. The app I?m working on is indeed an exploratory data analysis tool for gene expression, which requires a bunch of bioconductor packages. I guess for now, my best solution is to divide my app into modules and load/unload packages as the user switch from one module to another. This brought me another question: it seems that unload package with the

Might this be related to the Linux version? I'm testing on one of our university servers, and they tend to be deprived of regular updates sometimes... (Dirk, sorry for sending you this twice.) > Sys.info() sysname "Linux" release

Has anyone had any luck with moving files outside of /tftpboot? Its been particularly frustrating in my environment to support files within this directory. Especially since I support three different architectures and need to differentiate their boot loaders, kernels, configs, initrd's, etc. I'd really like to symlink off to my AFS space and let the sysname values do the work. Is there a

R-developers: Duncan Murdoch suggested I move a post I started on r-help over here, since it is more at the developer level. Here is my question/challenge -- to my knowledge, there is not currently an official way to store a *package*'s options to a standardized location on a user's computer. Given that OS-level programs have standard preference locations, I was hoping to first assess:

I was wondering if it was possible in Prototype/Scriptaculous to run an effect when a link is clicked, then go to that page, or if it was possible to have an effect run when the page unloads. I have tried <body onunload="new Effect.Fade("whatever");> and some prototype page exit events, could get a alert("") function to work, but not the effects. Any ideas?

​No, sorry, it's actually failing on "configure" which this script calls. I should have been more clear. ./configured is failing at step: ​*Checking uname sysname type* It's obviously missing some app/header/library, but reading through all the breakpoints listed in the error (re-pasted below) I can't make out from the code what it's looking for, and the config.log

I set uniquename = MYHOST in asterisk.conf (under [options]) so that my uniqueid data shows up as MYHOST.time.seq. First of all, I would like to know if uniquename (or sysname?) will still be valid across future * versions (mainly 1.6). Secondly, is there a way to specify uniquename as an asterisk option at the command line? (asterisk -h doesn't show me anything regarding this feature)
