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.

This package does not use retiring packages in code, so may perhaps only use them in examples or vignettes apart from for raster. Although I know that mapsf is where development is occurring, I think fixing this here isn't very burdensome.

Sure, thanks for the heads up.
It's time to clean up the package a bit anyway.

Should be fixed now. CRAN submission to be done as soon as possible.
