Is Rcpp compatible with rpy2?
I would like to call a very complex R function from python. My function
depends on code implemented with Rcpp. When I try to load Rcpp from python
via
import rpy2.robjects as robjects
robjects.r('library(Rcpp)')
I get the following:
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object
'/home/jonas/R/x86_64-unknown-linux-gnu-library/2.13/Rcpp/libs/Rcpp.so':

>From what I understand R_ClassSymbol is supplied by libR.so, which should by

Running python 2.7.1, rpy2-2.2.2, R 2.13.0
I would appreciate any help.
Regards,
Jonas
