@AMBarbosa Check with: remotes::install_github("r-spatial/classInt", ref="q_probs"), you'll need Rtools on Windows or equivalent Fortran/C compilers elsewhere. If this is OK, I'll create a PR, check further and if still OK, merge, at which point it will appear in https://r-spatial.r-universe.dev/classInt.
