A new version of the sp package, 2.0-0, has been published on CRAN. This new
version defaults to using the sf package rather than the rgdal package, and
deprecates use of the rgeos package. These changes are described in
https://r-spatial.org/r/2023/05/15/evolution4.html, and lead up to the planned
archiving of the retiring packages: maptools, rgdal and rgeos in October 2023.
This version issues invasive start-up messages in order to alert users to
impending changes; maintainers of affected packages have already been warned.
