Yep: Making it easier to combine R and C++ by removing points of friction sadly does not automatically squash any bugs one may add (it's still software ...) so additional tooling can help. Also look at `spdl` putting a consistent wrapper for both the R and C++ side around `RcppSpdlog`. #rcpp #rstats

As there are 3100+ CRAN packages using #Rcpp giving you 3100+ examples. I rely on GitHub with tinytest; most of my packages do not bother with Windows or macOS CI. If it works on Linux, I can safe the cpu cycles. GitLab and Codeberg are used too, look for them. I do use winbuilder for spot checks.
