What is the problem?

Nice summary with this blog of the removal of rgal, rgeos, and maptools from CRAN. This can also affect older versions of the sp library. Lesson will need to be updated and remove function calls from these libraries.

Does this mean we can remove rgdal and rgeos from install, as well as geos and gdal? And proj4? It would simplify software installation a lot.

@jebyrnes I think they haven't been necessary for a while. I have an open PR on the workshop repo about removing that stuff.
