Vulnerability to absence of retiring r-spatial packages

[rsbivand]

00check.log
is a recent check log from running under _SP_EVOLUTION_STATUS_=2 without retiring r-spatial packages on the library path (see https://r-spatial.org/r/2022/04/12/evolution.html, https://r-spatial.org/r/2022/12/14/evolution2.html). This package has a strong dependency on maptools, maptools::gcDestination and possibly others in examples etc. maptools retires during October 2023, so an alternative should be found. The strong reverse dependencies of this package also fail in this check scenario.

Please also see https://r-spatial.org/r/2023/04/10/evolution3.html, fix best by June, latest October 2023.

@oswaldosantos See also https://r-spatial.org/r/2023/05/15/evolution4.html. Please take urgent steps to resolve this issue. No positive changes appear in the repository. Less than three months remain to retain this package on CRAN.

@oswaldosantos Less than three weeks remain to fix this.

@oswaldosantos R spatial infrastructure packages maptools, rgdal and rgeos will be archived by CRAN on Monday, October 16, 2023. Your package does not pass CMD check when these packages are not available. Expect your package to be archived by CRAN October 17-18 as CRAN checks feed through and your package fails, if not updated by Monday, October 16, 2023.

No grace period is anticipated, as you have had sufficient time to update your package to remove dependencies on maptools, rgdal and/or rgeos.
