parse_esri_json: Parse Esri JSON

Description

Parses an Esri FeatureSet JSON object into an R object. If there is no geometry present, a data.frame is returned. If there is geometry, an sf object is returned.

Usage

parse_esri_json(string, ..., call = rlang::caller_env())

Value

A data.frame. If geometry is found, returns an sf object.

Arguments

string

the raw Esri JSON string.

...

additional arguments passed to RcppSimdJson::fparse

call

The execution environment of a currently running function, e.g. call = caller_env(). The corresponding function call is retrieved and mentioned in error messages as the source of the error.

You only need to supply call when throwing a condition from a helper function which wouldn't be relevant to mention in the message.

Can also be NULL or a defused function call to respectively not display any call or hard-code a code to display.

For more information about error calls, see Including function calls in error messages.
