@mfansler rgdal, rgeos, maptools and rgrass7 were archived on CRAN 16 October 2023. They should have been withdrawn by all downstream aggregators at that point for R 4.3, certainly for R 4.4. None of the retired packages are being maintained and will fail when GDAL, GEOS, or PROJ (upstream libraries) cause breakages. As maintainer of the retired packages, I cannot be expected to alert all downstream package managers/aggregators. Sufficiently noisy warnings were inserted into the retired packages and into sp, which has been moved to sf to satisfy its needs for functionality from GDAL, GEOS, or PROJ. I will not notify anybody, that is not my responsibility, I have done what could be done with obvious cases or where contacted by users experiencing problems. See https://r-spatial.github.io/evolution/, and the video of https://edzer.github.io/UseR2024 when it is posted.
