Merci !
Both problem were solved by starting everything from begin (with Rcpp skeleton). Note that it took me time to understand that the aim of option module in the Rcpp.skeleton is not to help you introduce you module but produce something that you can modify with your own module name.
>From what I understood the only difference with what was before in my code is that
.onLoad <- function(libname, pkgname) {
loadRcppModules()
}
was replaced by loadModule("mymodule")
This solved the first problem (the "note" asking for methods)
so I tried to upload the package on CRAN and it worked ... second problem solved in the same time !
Again I'm really impressed of how easy it was to port c++ code with Rcpp module (not only high level function but objects and methods ...) on R, you guys are great !
Cheers
Robin

Salut Robin,
Welcome, at long last, to rcpp-devel.

| Dear rcpp-devel list,
|
| I am encountering 2 different problems with Rcpp modules (which by the way are sooo impressively great !) during the install phase of testmod,
|
| ---------1st problem
| while trying to check package testmod (to use module) I got :
|
| File 'testmod/R/zzz.R':
| .onLoad calls:
| require("methods", character = TRUE, quietly = TRUE)
You need to declare a dependency on the package "methods", just like the
error says.
| Package startup functions should not change the search path.
| See section 'Good practice' in ?.onAttach.
|
| .onLoad: warning in require("methods", character = TRUE, quietly =
| TRUE): correspondance partielle d'argument de 'character' par rapport 'character.only'
|
| (Windows R v2.15.2, last Rtools, ...)
| I'm not really used to all these package stuff and clearly do not understand what's happening. Any solution ?
|
| Actually I have the same error on another package I just tryied to submitt to CRAN but I guess that this won't be accepted ...
|
|
| -----------2nd problem
|
| My package was actually rejected on CRAN because it does not compile on Uwe Ligges's windows system, logs are attached and start like that
|

Your linling instructions are wrong.
So it looks like you have some fundamental issues here with package
construction. What I would do is the following:
a) Either start from scratch (say via rcpp.package.skeleto() with the
module=TRUE argument) to get a basic package using modules; try to then
expand that by including your code
b) Take an existing package from CRAN and examine it; for example my
RcppCNPy is pretty recent, used modules and is small.
Good luck, Dirk

| I do not understand the logs but I know 2 things :
| a- It compiles and works properly on my windows system (and on mac and linux actually).
| b- I had exactly the same error message 2 days ago while trying to run checks on testmod package and it get sorted when I updated my version of RTools. Is it possible that Uwe Ligges has an outdated version of Rtools ? or do you have any idea of where this can come from ?
