+# R packages overlay (rix)
+#
+# This overlay provides access to R packages from rstats-on-nix.
+#
+# rstats-on-nix maintains snapshots of CRAN packages built with Nix:
+# - Provides reproducible R package versions
+# - Ensures binary cache availability for faster builds
+# - Maintained by the rstats-on-nix community
+#
+# Available attributes after applying this overlay:
+#   - pkgs.rpkgs: R packages from rstats-on-nix
+#   - pkgs.rpkgs.rPackages: All CRAN packages
+#   - pkgs.rpkgs.quarto: Quarto publishing system
+#   - pkgs.rpkgs.rWrapper: R with package management
+#   - pkgs.rWrapper: R wrapper with standard packages pre-configured
+#   - pkgs.quarto: Quarto with R integration and standard packages
+#
+# Custom R packages and tools (radianWrapper, air-formatter) come from
+# the fran overlay which should be applied separately.
+#
+# To use specific R packages, reference them via:
+#   with pkgs.rpkgs.rPackages; [ package1 package2 ]
+#
+# Update the R snapshot date in flake.nix inputs section:
+#   rixpkgs.url = "github:rstats-on-nix/nixpkgs/YYYY-MM-DD"
