This might be a documentation issue on our side, but you don't need to
call Module. The code that is generated loads the module directly when
teh package is loaded:
> require( testmod )
Le chargement a nécessité le package : testmod
Le chargement a nécessité le package : Rcpp
> hello()
Erreur : boom
# this is expected, the hello function is supposed to
# throw an error
# something using a class:
> new( World )$greet()
[1] "hello"
Just see module as an implementation detail and a way to get access to
these functions.
Look at the code that is generated in the R and src directories for more
detail.

Hello,
Any help would be greatly
appreciated!!!!
I am trying to use the example
testmod package by using:
Rcpp.package.skeleton( "testmod", module = TRUE )
and:
R CMD INSTALL testmod
system information:
R version 3.0.1 (2013-05-16)
Platform: x86_64-pc-linux-gnu (64-bit),
ubuntu 12.04 LTS
/usr/local/lib/R/site-library/testmod/libs/testmod.so
Rccp 0.10.3 (build from source with as also RUnit, inline, rbenchmark)
What I've tried so far amongst other suggestions
found on the web:
Test 1:
> require(Rcpp)
Lade nötiges Paket: Rcpp
> yada <- Module( "yada", "testmod" )
> yada$hello()
Fehler in Module(module, mustStart = TRUE) :
Failed to initialize module pointer: Error in
FUN("_rcpp_module_boot_yada"[[1L]], ...): no such symbol
_rcpp_module_boot_yada in package testmod
Test 2:
> require("testmod")
Lade nötiges Paket: testmod
Lade nötiges Paket: Rcpp
> yada$hello()
Fehler: Objekt 'yada' nicht gefunden
Test 3:
> library(Rcpp)
> library(testmod)
> yada <- Module( "yada", "testmod" )
> yada$hello()
*** caught segfault ***
address 0xd8, cause 'memory not mapped'
Traceback:
1: .Call(symbol)
2: Module(module, mustStart = TRUE)
3: .getModulePointer(x)
4: yada$hello
Any help would be
great, because I want to
use my existing C++ classes
in a R package and it
would be great to have a starting
point.
Best regards,
Andreas
