Dear all,
I am struggling accessing a class created in an Rcpp module.
The structure of the package is essentially the one created using:
Rcpp.package.skeleton(name="testPackage",module=TRUE)
Now, after loadiong the package with library(testPackage), I can create
instances of the "World" class as follows:
library(testPackage)
mod_yada<-Rcpp::Module("yada",PACKAGE="testPackage",mustStart=TRUE)
w <- new(mod_yada$World);
So far so good.
However, I fail defining a S4 wrapper class within the same package. As
part of that, I would like to define a generator function that returns
an instance of mod_yada$World, as in the code above:
However, "yada$World" is not accessible.
I then tried inserting the following line in the respective R file
(although I thought this was already taken care by the
"loadModule("yada", TRUE)" that was places in zzz.R by the
skeleton
generator:
mod_yada<-Rcpp::Module("yada",PACKAGE="testPackage",mustStart=TRUE)
But again, this fails with:
Failed to initialize module pointer: Error in
FUN("_rcpp_module_boot_mod_yada"[[1L]], ...): no such symbol
_rcpp_module_boot_mod_yada in package testPackage
Putting this file after zzz.R in the Collate: list in the DESCRIPTION
file also does not help.
How can I define this in the Rcpp package itself?
Thanks for any hint
