[Rcpp-devel] R Embedded in a class function

[CESAR PERNALETE]

Hi Davor. 

Thanks for your response. Yes, the problem is the creation of  an embedded 
R instance inside a method. 
Attached there is a simplified example of the way i tried. 

As a context, i'm using NOMAD 
(http://www.gerad.ca/nomad/Project/Home.html), an optimization tool where 
the constraints are functions created in R. These constraints must be 
created in the method called eval_x. 

Please help.

If you have some specific code, that would help. If you by "class 
function" you mean to ask "is it possible to create an embedded R instance 
inside a method?", then the answer is "yes". But there are several things 
you may be doing incorrectly, and seeing your code would mean we can 
address the one that is the problem.
