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 | unit
The 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 ~ time
The observations in x
are
first aggregated
over units
and the resulting univariate time-series is plotted via the
function stsplot_time
.
alarm ~ time
Generates 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 ~ unit
produces a map of counts (or incidence) per region aggregated over
time. See stsplot_space
for optional arguments,
details and examples.
observed ~ 1 | unit
old version of the map plot, which
supports shading regions with an alarm.
The plotting is done by the function stsplot_spacetime
.
Use type=observed~unit
for the new implementation as function
stsplot_space
(without alarm support, though).
observed ~ 1 | unit * time
old version for animated
maps via the stsplot_spacetime
function.
Each of the nrow(x)
frames contains the
number of counts per region for the current row in the
observed
matrix. It is possible to redirect the output
into files, e.g. to generate an animated GIF.
NOTE: the new animate.sts
method supersedes this
plot type
