trainingData {ensembleBMA} | R Documentation |
Extracts the training data corresponding to a given date and training rule.
trainingData( ensembleData, date, trainingRule = list(length=30, lag=2))
ensembleData |
An ensembleData object including ensemble forecasts, observations
and dates of precipitation.
|
date |
The date for which the training data is desired. |
trainingRule |
A list giving the length and lag for the training period.
The default is to use a 30 day training period for a forecast
2 days ahead of the last day in the training period.
|
The training rule uses the most recent days for the given period regardless of whether or not they are consecutive.
An ensembleData
object corresponding to the training data for
the given date relative to ensembleData
