lawn_geosjontype | R Documentation |
Enforce expectations about types of GeoJSON objects.
lawn_geosjontype(x, type, name, lint = FALSE)
x |
value of any data-GeoJSON object. required. |
type |
expected GeoJSON type. required. |
name |
name of calling function. required. |
lint |
(logical) Lint or not. Uses geojsonhint. Takes up increasing
time as the object to get linted increases in size, so probably use by
default for small objects, but not for large if you know they are good
geojson objects. Default: |
nothing if no problems - error message if a problem
Other invariant:
lawn_collectionof()
,
lawn_featureof()
# all okay x <- "{ type: 'Point', coordinates: [10, 50] }" lawn_geosjontype(x, 'Point', 'fooBar') # error # lawn_geosjontype(x, 'Polygon', 'fooBar')
