Please remove dependencies on **rgdal**, **rgeos**, and/or **maptools**

[rsbivand]

This package depends on (depends, imports or suggests) raster and one or more of the retiring packages rgdal, rgeos or maptools (https://r-spatial.org/r/2022/04/12/evolution.html, https://r-spatial.org/r/2022/12/14/evolution2.html). Since raster 3.6.3, all use of external FOSS library functionality has been transferred to terra, making the retiring packages very likely redundant. It would help greatly if you could remove dependencies on the retiring packages as soon as possible.

Fails CMD check in a scenario using sp evolution status 2 (substitute use of rgdal with sf for projection/transformation/CRS) and absence of retiring packages from the library path; new blog https://r-spatial.org/r/2023/04/10/evolution3.html. Action needed soon!

See also https://r-spatial.org/r/2023/05/15/evolution4.html; make the required changes as soon as possible.

Only three months remain before rgeos is withdrawn.
