Hi folks, 

I want to use the cholmod functions from the modify module 
https://github.com/PetterS/SuiteSparse/tree/master/CHOLMOD/Modify inside an 
Rcpp/RcppEigen R package. 

>From my understanding, these functions are not exposed by Rcpp or RcppEigen

>(https://github.com/RcppCore/RcppEigen/blob/master/inst/include/RcppEigenCholmod.h)
> and the actual sources come from the Matrix package 
>https://github.com/cran/Matrix/tree/master/src/CHOLMOD. 

I've checked that the modify module is present in the src folder of the Matrix 
package https://github.com/cran/Matrix/tree/master/src/CHOLMOD/Modify but I'm 
lost on how to proceed in order to be able to use it. 
Any help on the best way to achieve this will be greatly welcome. 

Thanks a lot. 

Etienne
