data_frame_from_forecast_data(forecast_data)

Arguments

forecast_data

Forecast data as a list in the Zoltar standard format

Value

A data.frame from forecast_data in zoltar-specific format. The columns are: 'unit', 'target', 'class', 'value', 'cat', 'prob', 'sample', 'quantile', 'family', 'param1', 'param2', 'param3'. They are documented at https://docs.zoltardata.com/fileformats/#forecast-data-format-csv . NB: columns are all character (i.e., data type information from forecast_data is lost). Also note that a retracted prediction element is represented as a single row with NA values for all but the first four columns.

Examples

if (FALSE) {
  forecast_data <- jsonlite::read_json("docs-predictions.json")
  data_frame <- data_frame_from_forecast_data(forecast_data)
}
