The link suggested by Ben is over 7 years old, so using the CRAN Task View: https://cran.r-project.org/web/views/Spatial.html, which is up-to-date, and https://rspatial.org/index.html, because the terra package has largely replaced the raster package. Please consider following up on the R-sig-geo mailing list: https://stat.ethz.ch/mailman/listinfo/r-sig-geo.
