Sometimes you may get a response that your input GeoJSON is
invalid, but get a somewhat unhelpful error message, e.g.,
no (or more than one) schemas match
. See
https://github.com/ropensci/geojsonlint/issues/7#issuecomment-219881961.
We'll hopefully soon get this sorted out so you'll get a meaningful error
message. However, this method is faster than the other two methods in
this package, so there is that.
TRUE
or FALSE
. If inform=TRUE
an attribute
of name errors
is added with error information
