is_complete: Indicates if the time series is complete
Description
This function indicates if the time series is complete, meaning that the time
steps are equally spaced and there are thus no gaps in the time series.
Usage
is_complete(x)
Value
logical. TRUE if the time series is complete, with no gaps;
FALSE otherwise. If no offsets have been added to the CFTime instance,
NA is returned.
Arguments
x
An instance of the CFTime class.
Details
This function gives exact results for time series where the nominal
unit of separation between observations in the time series is exact in
terms of the calendar unit. As an example, for a calendar unit of "days" where the
observations are spaced a fixed number of days apart the result is exact, but
if the same calendar unit is used for data that is on a monthly basis, the
assessment is approximate because the number of days per month is variable
and dependent on the calendar (the exception being the 360_day calendar,
where the assessment is exact). The result is still correct in most cases
(including all CF-compliant data sets that the developers have seen) although
there may be esoteric constructions of CFTime and offsets that trip up this
implementation.
