This function verifies if the difference in dates within each date in the
provided observations corresponds to the provided timestep. This check is
performed for both report_date and reference_date and for each group in
obs.
Arguments
- obs
Any of the types supported by
data.table::as.data.table().- timestep
The timestep to used. This can be a string ("day", "week") or a numeric whole number representing the number of days. Note that "month" is not currently supported in user-facing functions and will throw an error if used.
- exact
Logical, if
TRUE, checks if all differences exactly match the timestep. IfFALSE, checks if the sum of the differences modulo the timestep equals zero. Default isTRUE.
Value
This function is used for its side effect of checking the timestep
by date in obs. If the check passes for all dates, the function
returns invisibly. Otherwise, it stops and returns an error message.
