That's odd that it only happens for your package. Guess #2 is that it
might be a namespace issue. Can you try adding:
import(methods)
import(Rcpp)
to your NAMESPACE file

That exposes the data3 class, but does not solve the pointer problem.

I updated to the new Rcpp 0.8.9 then added a new function to my

get the error:

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

2: function (object)

Thanks,

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.
