similar to: setMethod call in package code using Rcpp

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

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 list, Calling setGeneric()/setMethod() from within the .onLoad() hook of MyPkg package produces the following error: > gctorture(TRUE) > library(MyPkg) .onLoad(): ok1 .onLoad(): ok2 Error : protect(): protection stack overflow Error : .onLoad failed in 'loadNamespace' for 'MyPkg' Error: package/namespace load failed for 'MyPkg' This is with

Hi all. I started looking at Rcpp, which looks pretty great, actually. At the moment just trying to compile a module to get a feel how it all works without fully understanding how all the pieces fit together. Basically, i took the first example from Rcpp modules vignette: fun.cpp ======================== #include <Rcpp.h> #include <math.h> using namespace Rcpp; double

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".

Hi, I have a issue loading Rcmdr today. It is very strange, as I could get it to work last week on the same computer. I have tried restarting the computer, and re-installing R and XQuartz, but nothing changes. This is what I get: sessionInfo() R version 3.2.4 (2016-03-10) Platform: x86_64-apple-darwin13.4.0 (64-bit) Running under: OS X 10.11.4 (El Capitan) locale: [1]

Hi Henrik, A bit late, but you can take a look at smbache's {import} package [1] in case you didn't know it. I believe it does what you are describing.

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

gccld would barf if you tried to specify the full pathname of an archive on the command line to gcc, (e.g., instead of gcc ... -L/full/path/to -lFOO you say gcc ... /full/path/to/libFOO.a) which many GNU Makefiles try to do. This patch fixes that. Ok to commit? -- gaeke at uiuc.edu gccld.cpp: Fix typo in header. Add IsArchive static method. Roll LoadLibraryFromDirectory() into

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.

Anton, Thanks for your comment. 2nd patch attached. - s/SharedDir/SharedLibDir/g - move prefix=cyg sunk into if(cygwin or mingw) arigato gozaimasu...Takumi * Additional issues - You may build LLVMHello.dll but I don't modify lib/Transforms/Makefile. Because making LLVMHello.dll requires the library LLVM.dll, but it oughta be on the way to making libs at building
