plot.seasonal: Seasonal Diagnostic Plot for an stl2 Object

In hafen/stl2: Implementation of Seasonal-Trend Decomposition using Loess (STL) in R

Description

Plots each cycle-subseries of the detrended data (or equivalently, seasonal plus remainder), with the mean subtracted. The fitted seasonal component is plotted as a line through the points.

Usage

plot.seasonal(x, col = c("black", "red"), lwd = 2, xlab = "Time", 
    ylab = "Centered Seasonal + Remainder", ...)

Arguments

x	object of class "stl2".
col, lwd, xlab, ylab, ...	parameters to be passed to xyplot().

Details

Helps decide how much of the variation in the data other than the trend should go into the seasonal component, and how much in the remainder.

Value

object of class "trellis".
