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.
