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
