Hi Zachary, FYI, I found these broken links in your RcppML pkgdown site.

The link to this tutorial can't be reached -

• https://zdebruine.github.io/RcppML/articles/annotating_nmf_models.html

The output plots from these sections are missing-

• https://zdebruine.github.io/RcppML/articles/getting_started.html#predictionrecommendation-with-nmf

• https://zdebruine.github.io/RcppML/articles/getting_started.html#cross-validation-for-rank-determination
