I updated to the new Rcpp 0.8.9 then added a new function to my class.<br>
It compiles fine the Module is found and loads the class definition<br>
seems to be there, but when I try to create a instance of the class I<br>
get the error:<br>
<br>
R> new(Module("GPU_BAYES",'gpuBayes')$data3)<br>
Error in get(".pointer", envir = env) : object '.pointer' not found<br>
<br>
Any Ideas what might be wrong here? That's a rather vague error. The<br>
traceback gives<br>
<br>
> traceback()<br>
3: get(".pointer", envir = env)<br>
2: function (object)<br>
standardGeneric("show")(<S4 object of class "Rcpp_data3">)<br>
1: function (object)<br>
standardGeneric("show")(<S4 object of class "Rcpp_data3">)<br>
<br>
<br>
Thanks,<br>

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:<br>
<br>
# grab the namespace<br>
NAMESPACE <- environment()<br>
<br>
.onLoad <- function(libname, pkgname){<br>
# load the module and store it in our namespace<br>
yada <- Module( "GPU_BAYES" )<br>
populate( yada, NAMESPACE )<br>
}<br>
<br>
and the "data3" class is directly exposed in the namespace of your package, so that you can do:<br>
<br>
new( data3 )<br>
<br>
Does that work ?<br>
<br>
<br>
Otherwise, maybe you can try adding mustStart = TRUE to the call to Module.<br>
