Synopsis
This package provides R with access to Abseil header files.
This package is a direct import of Abseil libraries.
It can be used via the LinkingTo: field in the DESCRIPTION field of an R package — and the R package infrastructure tools will then know how to set include flags correctly on all architectures supported by R.
