I updated to the new Rcpp 0.8.9 then added a new function to my class.
It compiles fine the Module is found and loads the class definition
seems to be there, but when I try to create a instance of the class I
get the error:
R> new(Module("GPU_BAYES",'gpuBayes')$data3)
Error in get(".pointer", envir = env) : object '.pointer' not found
Any Ideas what might be wrong here? That's a rather vague error. The
traceback gives
> traceback()
3: get(".pointer", envir = env)
2: function (object)
standardGeneric("show")(<S4 object of class "Rcpp_data3">)
1: function (object)
standardGeneric("show")(<S4 object of class "Rcpp_data3">)
Thanks,
Andrew
In the Rcpp-modules vignette, that has been considerably updated in the
last version of Rcpp (part of the 8661 new lines of code), we suggest to
have this in your .onLoad:
# grab the namespace
NAMESPACE <- environment()
.onLoad <- function(libname, pkgname){
# load the module and store it in our namespace
yada <- Module( "GPU_BAYES" )
populate( yada, NAMESPACE )
}
and the "data3" class is directly exposed in the namespace of your
package, so that you can do:
new( data3 )
Does that work ?
Otherwise, maybe you can try adding mustStart = TRUE to the call to Module.
