valid_arg_level: Validate arguments
In SUN-Wenjun/fbicrime: R wrapper for FBI Crime API
Description
valid_arg_level() is a function used to validate the arguments for level and level_detail.
Usage
1
valid_arg_level(level, level_detail)
Details
This function is intended to be called by other querying functions within the fbicrime package, but not for external call by users.
It checks two things:
1) whether the input level is legal (i.e. one of 'agencies', 'national', 'regions', 'states');
2) whether the input level matches level_detail.
This function produces an error when level is 'national' but level_detail is not NULL,
and when level is not 'national' but level_detail is NULL or is not specified.
