plot_cycle function

Cycle-Subseries Plot for an stlplus Object

Plots the seasonal component by cycle-subseries, with lines emanating from the midmean of the values within each cycle-subseries.

plot_cycle(x, layout = c(x$pars$n.p, 1), col = "#0080ff", xlab = "Time",
  ylab = "Seasonal", panel = function(x, y, ...) {    
  lattice::panel.segments(x, rep(.midmean(y), length(x)), x, y, col = col) },
  ...)

Arguments

• x: object of class "stlplus".
• layout, col, xlab, ylab, panel,: parameters to be passed to xyplot().

Returns

object of class "trellis".
