similar to: loading a package .Rda file at package load time

Dear all, I just found that some of the packages are not able to load any more, after I installed R2.0.1 in my Mac, it even affects my old R1.8 installs. It gives me errors when I load packages that contains "myEnv" settings. such as: RMySQL, DBI, Rggobi, etc. But others that does not require "myENV" is all right, like tcltk that only calls the c functions. The errors

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 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

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 <-

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 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

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'm creating a package for my own use that uses some S4 classes but no methods. I have a file called NAMESPACE it contains the line: exportClasses("foo") and at the top of the R file I have setClass("foo", representation(x="numeric") and the line: .onLoad<-function(libname,pkgname) When I run R CMD check I get Syntax error in the only R file. If I

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.

Hello! I installed rJava and am trying to load it. library(rJava) Error : .onLoad failed in loadNamespace() for 'rJava', details: call: fun(libname, pkgname) error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures. Error: package or namespace load failed for ‘rJava’ Any idea why? Background info:

Hello, all I am building a R package using Fortran source code. The Fortran code is a subroutine. I can use "R CMD SHLIB bar.f -o bar.o" to create the shared library. For the R package, I put the fortran file in the src/ and I use R code as follows: ".First.lib"<-function(libname,pkgname){library.dynam("barpkg",pkgname,libname)} barfun<-function(n,x){

I just bought a new machine and installed the latest release of R 2.15.1 two days ago. Loaded libraries yesterday (all reported successful loads). While running scripts, rJava and Snowball would not load. Here is Snowball successful install: > utils:::menuInstallPkgs() trying URL 'http://cran.cs.wwu.edu/bin/windows/contrib/2.15/Snowball_0.0-8.zip' Content type

Dear r-help group, I am creating a package that has some FORTRAN code under windows. I have read through "Writing R Extension" but still not so clear about the steps. Before R CMD build, how can I create a dynamic library and later in my R function using dyn.load ("xxx.dll") ? If I already have a .dll file, can I build the package with the dll file directly ? Does any one

R-1.4.0 seems to have changed the way delay() works, or perhaps it is the way library() works that nullifies the advantages of using delay() in a package. It seems that the process of loading a package evaluates each object provided by that package, and so in particular, the delay()ed object is evaluated and brought into memory. For example generating a test example, where test/R/functions.s is:

I run R 1.9.0 on windows 2000, and have the following libraries installed: affydata_1.3.1 affy_1.4.23 Biobase_1.4.10 DynDoc_1.3.14 gcrma_1.0.6 hgu133acdf_1.4.3 hgu95av2cdf_1.4.3 hgu95av2probe_1.0 matchprobes_1.0.7 moe430acdf_1.4.3 multcomp_0.4-6 mvtnorm_0.6-6 rae230acdf_1.4.3 reposTools_1.3.29 rgu34acdf_1.4.3 tkWidgets_1.5.1 widgetTools_1.2.7 1. The rma function (in affy library) always crashes.

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

Hi, I've been slowly transitioning to saving sets of objects for a project using save() rather than cluttering my workspace and then doing save.image() However, sometimes after I have done say: save(x,y,z, file='work.Rda') and I reload it a little later and I see that I also want to save object p. Currently I need to do: save(x,y,z,p, file='work.Rda') Is there any way
