Functions that can return appropriate graphic attributes (i.e. color interpolation) based on properties of the network (ages of edges,etc)
effectFun(name, ...)
effect.edgeAgeColor (net, onset, fade.dur,
start.color = "#000000FF", end.color = "#00000000",
na.color = "#CCCCCC55")
effect.vertexAgeColor (net, onset, fade.dur, start.color = "#000000FF",
end.color = "#00000000", na.color = "#CCCCCC55")effectFun returns the function named by its first argument, with any arguments matching in ... substituted.
the short name of the effect function to be returned. i.e 'edgeAgeColor' will return the effect.edgeAgeColor function
additional arguments to be passed in to effect functions
a network object to be evaluated
the time at which the network should be evaluated
(effect property) numeric value giving the color duration of the interpolation
(effect property) color name for color value to be used at start of interpolation
(effect property) color name for color value to be used at start of interpolation
(effect property) default color name for color value to be used for edge/vertices that are not currently active

The special effects functions can be called directly for use as graphic parameters with standard network plots, or via effectFun which will return the effect in a functional form so that it can evaluated/substituted at each time point as plot control function to render.animation
effect.edgeAgeColor calculates the edge of each edge in net at the time onset and uses the value to return a color interpolated between start.color and end.color by comparing the time of each edge to the fade.dur parameter
effect.vertexAgeColor does the same, but for vertices.
Users can also define functions to be called in this way
