assorthead 1.1.0
assorthead vendors an assortment of header-only C++ libraries for use in Bioconductor packages. The use of a central repository avoids duplicate vendoring of libraries across multiple R packages, and enables better coordination of version updates across cohorts of interdependent C++ libraries. This package is minimalistic by design to ensure that downstream packages are not burdened with more transitive dependencies.
To use assorthead in a Bioconductor package,
just add it to the LinkingTo field in the DESCRIPTION:

The beachmat package contains the initializeCpp() function, which creates an external pointer to a tatami::Matrix.
Similarly, the BiocNeighbors package can create external pointers to various knncolle objects via its defineBuilder() and buildIndex() functions.
Downstream packages can use these pointers in their own C++ code by compiling against the relevant interfaces in assorthead.
This means that downstream packages do not need to re-compile all of the relevant header libraries to get full functionality of beachmat, BiocNeighbors, etc.
It also allows the C++ code of downstream packages to handle extensions to each framework, e.g., new matrix types in beachmat.hdf5.
Check out each of the packages for more specific instructions on how to use its external pointers.
