parent_function_error

Creates a function that raises an error that is assigned to the function in
which the error was originally seen. Useful to prevent big repetitive
<code>gtfsio_error()</code> calls in the "main" functions.

Tools for the development of packages related to General
Transit Feed Specification (GTFS) files. Establishes a standard for
representing GTFS feeds using R data types. Provides fast and flexible
functions to read and write GTFS feeds while sticking to this
standard. Defines a basic 'gtfs' class which is meant to be extended
by packages that depend on it. And offers utility functions that
support checking the structure of GTFS objects.
