arguments passed to the type-specific plot
function.
There are various types of plots which can be produced from an
"sts" object. The type argument specifies the desired
plot as a formula, which defaults to observed ~ time | unit,
i.e., plot the time series of each unit separately. Arguments to
specific plot functions can be passed as further arguments (...).
The following list describes the plot variants:
observed ~ time | unitThe default type shows
ncol(x) plots, each containing the time series of one
observational unit. The actual plotting per unit is done by the
function stsplot_time1, called sequentially from
stsplot_time.
A ggplot2-based alternative for this type of plot is
provided through an autoplot-method
for "sts" objects.
observed ~ timeThe observations in x are
first aggregated over units
and the resulting univariate time-series is plotted via the
function stsplot_time.
alarm ~ timeGenerates a so called alarmplot for a
multivariate sts object. For each time point and each
series it is shown whether there is an alarm. In case of
hierarchical surveillance the user can pass
an additional argument lvl, which is a vector of the
same length as rows in x specifying for each time series
its level.
observed ~ unitproduces a map of counts (or incidence) per region aggregated over
time. See stsplot_space for optional arguments,
details and examples.
