Thanks! I'm still 'R' illiterate and your example is (yet another) incentive to get myself into the language. What most annoyed me is the diversity in the nomenclature for the same thing (NORTH/NORTHING/LATITUDE and EAST/EASTING/LONGITUDE), perhaps subtle details I'm not aware, considering EPSG was some coordinated initiative.
Other thing that's great about doing it is knowing more what's inside proj.db. Interesting tables.
[('alias_name',), ('authority_to_authority_preference',), ('axis',), ('celestial_body',), ('compound_crs',), ('concatenated_operation',), ('concatenated_operation_step',), ('conversion_method',), ('conversion_param',), ('conversion_table',), ('coordinate_operation_method',), ('coordinate_system',), ('deprecation',), ('ellipsoid',), ('extent',), ('geodetic_crs',), ('geodetic_datum',), ('geodetic_datum_ensemble_member',), ('geoid_model',), ('grid_alternatives',), ('grid_packages',), ('grid_transformation',), ('helmert_transformation_table',), ('metadata',), ('other_transformation',), ('prime_meridian',), ('projected_crs',), ('scope',), ('sqlite_stat1',), ('sqlite_stat4',), ('supersession',), ('unit_of_measure',), ('usage',), ('versioned_auth_name_mapping',), ('vertical_crs',), ('vertical_datum',), ('vertical_datum_ensemble_member',)]
east and north, easting and northing, is a misnomer - x and y makes sense but east and north do not generally
thanks for this cool example!
Here's a stab at an R version, not sure my logic is sound yet but this is great for me to compare R and python approaches
