similar to: Custom per-package options passed down via library() ?

I'm currently working on a new package for R that interfaces with an API. Most of the package's functionality requires users to supply an access key that allows the package to work with the API. I want to display text immediately upon loading the package that instructs/reminds users to enter their access key before attempting to do anything (as the package won't really work without

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

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 R-devels, in "Writing R extensions" as well as in the help to .onAttach(), you mention that one could use this function to issue a start-up message/banner for the package. My little wish for Easter: a 'quietly'-type argument for .onAttach() / .First.lib() which is passed through by functions require() and library() respectively, and by means of which one could optionally

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

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 <-

I am attempting to build a package on r-forge and running into a weird error. I have been in correspondence with the R-forge admins and am turning to r-devel on the remote chance that someone might have a guess as to what is going wrong or a suggestion about further diagnostics/experiments I could try ... The package seems to build fine on my system(s) with R CMD build --compact-vignettes

Hello, (Dear Richard, I hope you don't mind being Cc:'d on this thread in R-devel. This is one of the ways we can prevent similar problems from happening in the future.) Sometimes, package authors who use both exportPattern('.') and utils::globalVariables(...) get confusing WARNINGs about undocumented exports: https://stat.ethz.ch/pipermail/r-package-devel/2024q1/010531.html I

Couldn't R simply regard .First.lib as the appropriate function to save many packages from being needlessly changed?

The Hmisc package has in its .First.lib function a verbose argument, which I thought was the way to allow users to suppress certain messages, by issuing library(Hmisc, verbose=FALSE). But I see that library( ) does not pass verbose to .First.lib. The default for verbose in Hmisc is TRUE because .First.lib prints some important information about masked functions. What is the best way to fix

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.

Dear developeRs, I have a package, pls, that implements package options. The users are supposed to use a function pls.options() to manipulate them. If a user changes the options, they are stored in .GlobalEnv. I was recently informed that this is against current CRAN submission policies, so I need to change that. I have looked at several different packages that implement package options, and

Documentation on how to put classes and methods in packages with namespace? How should I define my classes and methods in "dynamicGraph"??? (That is - Can some one point me to the documentation on how to put classes and methods in packages with a namespace? ) Currently it is done by the code below. This gives problems, when a workspace with a "dynmaicGraph" is

Calling library(..., quietly=TRUE) may still output: Loading required package: <other pkg> in some cases, e.g. > library("R.utils", quietly=TRUE) Loading required package: R.methodsS3 [...] I traced this to base:::.getRequiredPackages2(), which forgets to pass 'quietly' to an internal library() call: if (!attached) { if (!quietly)

Hi, I have just installed R 2.4.0 and when I try to load SpareseM, I get the following error message library(SparseM) Package SparseM (0.71) loaded.
