Hi Dirk, Thanks for your response. I've managed to deal with cholmod directly by copying it in my src as you suggested. This create conflicts with RcppEigen but since i was using it only to access the cholmod functionalities it will be ok for my use case.

Right. All this goes back to careful work by Doug back when his hierarchical model code predominantly relied on (Rcpp)Eigen. | 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. Well that is a different package, namely Matrix. We have some examples of sharing / exporting code between packages. But to a very first approximation ... if you just want to get going, maybe make a copy of Modify/ in your package? Assumming, of course, there are no conflicts with the other exported interfaces from Matrix and RcppEigen.
