plot_predictions {vctsfr}

Creates a ggplot object with a time series and some forecasts

Description

Create a ggplot object with a time series and, optionally, some future values of the time series and several forecast for those future values.

Usage

plot_predictions(ts, future = NULL, predictions = NULL, sdp = TRUE)

Arguments

ts

a time series of class ts.

future

NULL (default) or a time series of class ts or a vector. Future values of the time series.

predictions

NULL (default) or a named list containing the predictions for the future values. Each component of the list should contain a vector or an object of class ts representing a forecast, the name of the component should be the name of the forecasting method.

sdp

logical. Should data points be shown? (default value TRUE)

Details

If future or the forecasts in the prediction list are vectors then they are supposed to start after the last data of the time series.

Value

The ggplot object representing the time series and its forecast.

Examples

# plot a time series, its future values and two forecasts
ts <- window(USAccDeaths, end = c(1977, 12))
f <- window(USAccDeaths, start = c(1978, 1))
prediction1 <- rep(mean(ts), 12)
prediction2 <- as.vector(window(ts, start = c(1977, 1)))
p <- list(Mean = prediction1, Naive = prediction2)
plot_predictions(ts, future = f, predictions = p)
