Legacy packages maptools, rgdal, and rgeos support and switching to sf package?

[wkumler]

Hi all, neat package here. Upon updating to a newer version of R I've started getting warnings upon load about a few packages that this depends on retiring in October. Is this going to affect the package functionality?

> library(marmap)
The legacy packages maptools, rgdal, and rgeos, underpinning the sp package,
which was just loaded, will retire in October 2023.
Please refer to R-spatial evolution reports for details, especially
https://r-spatial.org/r/2023/05/15/evolution4.html.
It may be desirable to make the sf package available;
package maintainers should consider adding sf to Suggests:.
The sp package is now running under evolution status 2
     (status 2 uses the sf package in place of rgdal)
Registered S3 methods overwritten by 'adehabitatMA':
  method                       from
  print.SpatialPixelsDataFrame sp  
  print.SpatialPixels          sp

Hi, only a few functions should be affected. We'll do our best to update the package before any meaningful functionality is impacted. Feel free to get back to us if you see weird/unexpected behaviour in the next few months! ;-)
