[Rcpp-devel] using SparseSuite and RcppEigen in package

Hi Dirk,

Thanks for your suggestion - I had thought of doing that but it requires 
tracking the versions of SuiteSparse used by Matrix, which means extra 
maintenance work. OTOH maybe updates are rare enough that it's not worth 
worrying about. It'd be nice if Matrix could expose more of SuiteSparse, 
though, I'm sure I'm not the only one who needs that stuff.

Best

Simon

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!

I know "some" (eg rstan) have completemented the BH package with local
headers when BH was missing what they needed (as BH grew, I think we by now
added all they need).  So you could just do that, being careful to stick with
the same version.

Or would Yixuan's RSpectra help?  https://cran.r-project.org/package=RSpectra
