I am maintaining an R package for spatial data. When I run checks on R-devel (Windows), I get: "Warning: multiple methods tables found for 'direction'"
, which prohibits me from resubmitting my R package. I've checked and there is only one function direction()
which is from the raster
package - a package I don't explicitly import, but is suggested in sf
which I do. Any ideas of what this could be/a workaround?

It looks as though both raster and terra define these generics, terra 1.5-12 was just published. Resolution: https://github.com/rspatial/terra/issues/485#issuecomment-1012466626, re-install raster after terra.
