plot
method for class "fv_forecast". The type of plot
produced can be controlled using the target
and type
arguments with the
latter only being functional when target
is set to "posterior" or
"forecast".
Usage
# S3 method for fv_forecast
plot(x, obs = NULL, target = "posterior", type = "cases", ...)
Arguments
- x
A
data.table
of output as produced byforecast()
of class "fv_forecast".- obs
A data frame of observed data as produced by
latest_obs()
.- target
A character string indicating the target object within the
forecast()
to produce plots for. Current options are: posterior predictions ("posterior"), posterior forecasts ("forecast"), and the model fit ("fit"). When "posterior" or "forecast" are used thenplot.fv_posterior()
is called whereas when "fit" is usedplot_pairs()
is used.- type
A character string indicating the type of plot required, defaulting to "cases". Current options are: "cases" which calls
plot_cases()
, "voc_frac" which callsplot_voc_frac()
, "voc_advantage" which callsplot_voc_advantage()
, "growth" which callsplot_growth()
, "rt" which callsplot_rt()
, and "all" which produces a list of all plots by callplot_posterior()
.- ...
Pass additional arguments to lower level plot functions.
