similar to: unloading compiled code.

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'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.

Hello! I'm encountering a bug with samba shares, rsync and hard links. I was trying to investigate why on my "linksys" samba share i wouldn't get any hard link transferred and rsyncs to it would take forever. To keep a long story short, here's the output of the command, which should be pretty explanatory :-) mount says that: //192.168.0.105/DISK on /samba/linksys type

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") {

I'm hoping to migrate to dovecot from qpopper, with the eventual goal of enabling IMAP. However, my qpopper installation is fairly specialized, so I thought I'd ask here to see if anyone could get me headed down the best path. Here's the situation. I'm running FreeBSD and have a virtual domains setup with an extremely hacked LDA to do delivery to mailboxes within hashed

Hello all, I hope someone can help me, I have been testing out Dovecot to switch from popa3d which I use at the moment. When I get several users connecting and disconnection multiple times, the Dovecot process with command Auth uses 50-90% of the CPU for the period which they are connecting. I am wondering if there is something that I may have misconfigured, or if there is something that I can

Hi, Has something changed regarding the useDynLib in the NAMESPACE file in packages? I've written a package that works in e.g. 2.12/2.13 but simply cannot find the dynamic library under windows. The version on CRAN is older than the one I'm talking about and depends on a newer version of R but I want to make the package available to people with older versions. >

I'm not sure if this is the official behavior but I would expect the na.action function applied to a lm object to return the na.action. Here is what I mean. > x<-0:10 > y<-x+rnorm(10) Warning message: In x + rnorm(10) : longer object length is not a multiple of shorter object length > y[5]<-NA > m<-lm(y~x) > m$na.action 5 5 attr(,"class") [1]

I'm having a problem with the error and warning functions. I've tried this on multiple machine so I'm fairly sure it's not machine dependent and I've tried it on the latest versions 2.6.0-2.7.1. Whenever my program gets to an error or warning it crashes the entire program rather than throwing the error like it should. Here are the relevant bits. ... char const * const

Hi, I wonder whether a package with namespace & dynamic library can be installed with the version number attached, ie. with the argument --with-package-versions. Is this currently possible? Using R 1.9.1 on Debian 3.0 I encounter a problem when trying to load a package installed with R91 CMD INSTALL --with-package-versions -l /mnt/local/R/R-1.9.x-libs-EpiR RIO in R started with R91

I am developing a package that is only applicable on windows, is there a line I can put in the depends field of the DESCRIPTION file to tell that this should only be build for windows? Are there any other protocols that I should follow? Thanks, -- Andrew May the Open Source be with you. [[alternative HTML version deleted]]

Hello - I am making a first attempt at writing a simple C++ routine to print out R objects (this is a simple proof-of-concept as part of a larger package development). The relevant C++ routine is as follows: void Rwrite(SEXP fd, SEXP msg) { int *ofd = INTEGER(fd); const char * omsg = CHAR(asChar(msg)); printf("[%i] %s",*ofd,omsg); } And the corresponding interface in R is as

Now I try to add some C and Fortan code to my package, so the NAMESPACE file is useDynLib(eha) importFrom(survival, Surv) export(mlreg.fit, risksets) but I get ..... * checking R files for library.dynam ... OK * checking S3 generic/method consistency ... WARNING Error in .try_quietly({ : Error in library(package, lib.loc = lib.loc, character.only = TRUE, verbose = FALSE) :

hi! I tried to build a very simple package with NAMESPACE file, such that datasets are loaded only dynamically. > a2 <- function(x=a1) x+4 > a1 <- 1:10 > package.skeleton("aaa", list=c("a1", "a2")) Then I modified the help files and added the file NAMESPACE with these 2 lines: useDynLib(aaa) export(a1, a2) Then "R CMD BUILD aaa" works

Greetings I have a bunch of NAs in a column of categorical variables designating the size classes (e.g., smallest to largest: 1,2,3,4) of cave crickets. I'd like to substitute "U" (for unknown) for the NAs. Can anyone give me an idea how to do this? Thanks in advance.

hi Andrew Many thanks for the suggestion. I gave it a try , but still get the same issue - a fresh Rgui window (just one) opens, with an empty .RData, when I submit a script ( Ctrl & F8 ). I also tried running things as administrator, but it made no difference. Apparently windows 7 is selling like hot buns, so there should be enough market pressure before too long , to encourage the

hi, i'm having some trouble getting a package to load a shared library object in .onLoad(...) i have a shared object file, say "mylib.so". if i start an R session, and via the CLI specify the actual library via: > dyn.load("mylib.so") everything works quite well (i.e. i can then follow with some .Call (...) methods) now, i'd like to include this shared library in
