Produces a plot of a decomposition created by sabl.
USAGE:
sablplot(y, title="")
REQUIRED ARGUMENTS:
y:
object containing components trend, seasonal and irregular,
typically the result of a call to the function sabl.
This may optionally contain the component calendar.
The decomposed series may be in a component named transformed
or y.
If it is not present, it is computed as the sum of
the trend, seasonal, irregular, and calendar (if present) components.
OPTIONAL ARGUMENTS:
title:
main title for the page of plots.
SIDE EFFECTS:
produces one page of plots composed of 4 or 5 separate plots:
the series that was decomposed (the transformed series),
the trend, seasonal, calendar (if there is one)
and irregular components.
To the right of each plot is a bar
which portrays the relative scaling of that plot; i.e., the bar spans the same
number of units in each plot.
DETAILS:
Takes an argument y of a decomposition created by sabl and produces a
page of 4 or 5 plots: The decomposed series and the components.
