Hi Igor,
I’ve a couple packages that have spatial data in them that I maintain. I’ve
opted to package up the data as a geopackage file and import it as an {sf}
object. Edzer Pebesma suggests this to circumvent changes in the {sf} package
from affecting native {sf} objects that are distributed as part of a package.
Maybe this is an option for you?
In https://github.com/adamhsparks/extractOz, see /inst/extdata for the
geopackage file and https://github.com/adamhsparks/extractOz/blob/main/R/data.R
for handling the data importing and making available in the R session on
package load.
Best,
Adam
