@rkbauer The new release does not remove the strong dependency on maptools, which will be archived from CRAN in a month's time. Please act now to remove the dependency completely, and also save other packages depending on yours.

@rkbauer oceanmap still imports maptools - remove urgently or move to suggests and condition on all use.

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.
