get_forecast_counts | R Documentation |
Given a data set with forecasts, this function counts the number of
available forecasts.
The level of grouping can be specified using the by
argument (e.g. to
count the number of forecasts per model, or the number of forecasts per
model and location).
This is useful to determine whether there are any missing forecasts.
