Validate an Observed Stop Events Table

Checks that a table conforms to the observed stop events schema (see observed-stop-events). Called internally by all converters and by the assembler; exported so external producers can verify their own tables.

Usage

rt2s_events_validate(events)

Arguments

events

A data.frame/data.table of observed stop events.

Value

The validated events table as a keyed data.table (invisibly usable in pipes); errors describe the first violation found.
