Dear all, My gRbase package imports functionality from the bioconductor packages graph, Rgraphviz and RBGL. To make installation of gRbase easy, I would like to have these bioconductor packages installed in connection with installation of gRbase, but to do so the user must use setRepositories() to make sure that R also installs packages from bioconductor. Having to call setRepositories causes

Hi, I am facing with a strange behaviour of isClass and extends when these are called in .onLoad in both R 2.12.1 and R 2.13.0. This is preventing my package from doing some object initializations at a proper place (i.e. in .onLoad). Suppose one defines two S4 classes in a package, and that one needs to check the inheritance between these two when loading the package (e.g. to validate slots

for the moment, I'm using: .onAttach <- function(libname, pkgname) { .bbg.db.conn <<- dbConnect(dbDriver("PostgreSQL"), user="blah","blah") } .onUnload <- function(libpath) { dbDisconnect(.bbg.db.conn) } which results in a hidden global variable in the global environment. I would prefer to make the assignment only in the package namespace.

Hi, I'm developing a package whose API is only meant to be used in other packages via imports or pkg::foo(). There should be no need to attach this package so that its API appears on the search() path. As a maintainer, I want to avoid having it appear in search() conflicts by mistake. This means that, for instance, other packages should declare this package under 'Imports' or

Dear all, My apologies for re-posting this question, but I have not found any solution to my problem so far. I also think that my post may have been overseen due to the posting time and high traffic on this list. I experience a problem in implementing a S4 class in a package and would appreciate your help in this matter. The class is implemented using Rcpp, which works well. I then extend

I am getting the error message: > library(Rcmdr) Loading required package: car Loading required package: MASS Loading required package: nnet Error : .onAttach failed in attachNamespace() for 'Rcmdr', details: call: structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class = "tclObj") error: [tcl] invalid command name "image".

Greetings - Is it possible, inside .First.lib, to find out the version number of the package that is being loaded? If only one version of the package has been installed, we could scan the DESCRIPTION file, something like .First.lib <- function(lib, pkg) { library.dynam("spatstat", pkg, lib) dfile <- system.file("DESCRIPTION", package="spatstat")

Have a question about the following NOTEs appearing on CRAN checks: > .onLoad calls: > require(methods) > > Package startup functions should not change the search path. > See section ?Good practice? in ?.onAttach. For years, I have had the following in my S4-requiring packages. ##--------------------------------------------------------------------- .onLoad <-

Hi, I installed "circular" package and I wanted to load it automatically when R starts up, so I added the following lines in file Rprofile.site, .First <- function() library(circular) When R starts up, it gives me the following error: ---------- Loading required package: boot Loading required package: graphics Loading required package: stats Error : .onAttach failed in

G'day all, After reading through "Writing R Extensions", Version 2.1.1 (2005-06-20), I thought the the following points might need clarifications or corrections. (I checked that these comments also hold for "Writing R Extensions", Version 2.2.0.) 1) When I ran "package.skeleton" recently, I noticed that the DESCRIPTION file and an entry `type'. This

Hi, I apologize for this often/old question. I found some hints but couldn't solve the problem so far. I have C functions (incl. the header files) as well as the R wrapper functions which I want to use for faster calculations. These functions are included in a R package. The installation process seems to be ok (no errors). I also can load the package without errors. But when I call the

Hi all, I'm very new to R. I have installed R 1.9.0 on Linux (Fedora). Now I got an self-made package comprising R functions as well as C-Code which are used in several R functions. I installed the package without any error (see install log below). Then, I checked in /usr/lib/R/library if the package izbi exists and it exists. But whenever I try to load the library on the command line I

Hi, I have seen the answer to this sometime before but I just can't find it again - pointers appreciated. I have a package that contains some data.frames saved as .Rda files in the data/ directory. When the package is loaded I would like to have them be available in the workspace (without the user having to explicitly load them using data(...)). If my package does not use a NAMESPACE, I can

Hi All, I've been working on updating the 'genetics' package. As a consequence of the upgrade, .First.lib() looks like: .First.lib <- function(libname, pkgname) { if (!require(combinat)) warning("Unable to load 'combinat' library. Function `diseq.ci' will fail.") require(gregmisc) genotype <-

Hi All, I have recently created an Rcmdr plugin package and it passed all the checks and was uploaded to CRAN. I then downloaded it from CRAN and tried running it from my local R program and received this error: ... Error in f(libname, pkgname) : could not find function "getRcmdr" Error in library(pkg, character.only = TRUE) : .First.lib failed for 'RcmdrPlugin.MAc' In my

The XML package relies on libxml2.dll (e.g., bundled with the CRAN binary) installed in library/XML/libs. Unfortunately, c:/WINDOWS/system32/libxml2.dll will be found and loaded before this. Is there any programatic solution? Thanks, Martin -- Martin Morgan Computational Biology / Fred Hutchinson Cancer Research Center 1100 Fairview Ave. N. PO Box 19024 Seattle, WA 98109 Location: Arnold
