In mem: The Moving Epidemic Method

Creates the animated graph of the surveillance of the current season

Description

Function memsurveillance.animated creates an animated surveillance graph for the current season.

Usage

memsurveillance.animated(
  i.current,
  i.epidemic.thresholds = NA,
  i.intensity.thresholds = NA,
  i.output = ".",
  i.animated.graph.file = T,
  i.animated.graph.file.name = "animated",
  i.fps = 2,
  i.loop = 0,
  i.remove = T,
  ...
)

Arguments

i.current	Current season weekly rates.
i.epidemic.thresholds	Pre and post epidemic threholds.
i.intensity.thresholds	Intensity thresholds.
i.output	Directory where graph is saved.
i.animated.graph.file	If a animated gif should be produced, or just the intermediate graphics
i.animated.graph.file.name	Name of the animated graph.
i.fps	Number of frames per second of the animated gif.
i.loop	Number of loops for the animated dif, 0 for Infinite.
i.remove	Remove partial graphs.
...	Additional parameters parsed to memsurveillance.

Details

Input data must be the current season and an object of class mem. The output graph contains the weekly rates series along with the epidemic and intensity threshols located at the exact situation where the epidemic started. If there is no epidemic yet, only the epidemic threshold is placed.

See memsurveillance for more details

Value

memsurveillance.animated writes a gif graph of the surveillance of this season.
