This is method for producing various plots of the decomposition results returned by this package.
# S4 method for decomp
autoplot(object, which = NULL, ...)A ggplot2-graphic object is returned, i.e. an object of classes
"gg" and "ggplot".
an object returned by the function deseats.
various plots can be selected either via a keyword or a number;
enter "facets" or 1 to show a facet plot of the estimated
time series components; enter "observations" or 2 to show the
input time series; enter "fitted" or 3 to show the observations
alongside the estimated trend with seasonality; enter "detailed_fit" or
4 to show the observations together with the fitted values and the trend;
enter "trend_season" or 5 to show the observations together with
the trend and with the seasonality (the latter shown around the series mean);
enter "residuals" or
6 to plot the both detrended and seasonally adjusted series; use
7 or "deseasonalized" to show the seasonally adjusted
series; enter 8 or "detrended" to plot the detrended
series; the
default is which = NULL which then lets you select a plot
interactively in the R console.

Author and Package Creator
Create predefined standard plots of the decomposition objects returned by the
deseats package, e.g. returned by the function deseats.
Plots are created in the ggplot2 plot style. The type of plot can be chosen
either interactively from the console, or the argument which can be
used to directly select the kind of plot to create (see also the description
of the argument which) within the function call.
If plot type 5 (which = 5) is selected, the estimated
seasonality will be displayed around the mean of the observations by default.
Setting the additional argument s_around to some other value, will lead
to the seasonality being displayed around that constant value.
