Dear all,

I'm trying to use some CHOLMOD functionality inside an R package (specifically, sparse Cholesky updates/downdates). There's an CHOLMOD/Eigen interface for that, but unfortunately the header I need is not shipped as part of either the Matrix package or the Rcpp package. The file is cholmod_modify.h, and it does appear in the src/ directory of the Matrix package, but not in the include/ directory.

If I include it by hand I risk version conflicts, because the rest of CHOLMOD is provided by the Matrix package via RcppEigen. What's the clean way of handling that? Thanks for your input!

Best

Simon Barthelme
