Description

Plots a time series with forecasts and prediction intervals.

Usage

## S3 method for class 'forecast':
plot(x, include, plot.conf = TRUE, shaded = TRUE, shadecols
                 = switch(1 + (length(x$level) > 1), 7, length(x$level):1),
                shadepalette=heat.colors(length(x$level)+2)[-1], lambda = NULL,
                 col = 1, fcol = 4, pi.col=1, pi.lty=2, ylim = NULL, main = NULL, 
                 ylab = "", xlab = "", ...)
## S3 method for class 'splineforecast':
plot(x,fitcol=2,...)

Arguments

x Forecast object produced by forecast.
include number of values from time series to include in plot
plot.conf Logical flag indicating whether to plot prediction intervals.
shaded Logical flag indicating whether prediction intervals should be shaded (TRUE) or lines (FALSE)
shadecols Colors for shaded prediction intervals
shadepalette Palette for shaded prediction intervals
lambda Box-Cox parameter. If present, function backtransforms data and forecasts using InvBoxCox.
col the colour for the data line.
fcol the colour for the forecast line.
pi.col If shade=FALSE and plot.conf=TRUE, the prediction intervals are plotted in this colour.
pi.lty If shade=FALSE and plot.conf=TRUE, the prediction intervals are plotted using this line type.
ylim Limits on y-axis
main Main title
ylab Y-axis label
xlab X-axis label
fitcol Line colour for fitted values.
... additional arguments to plot.
