plot.bursts {bursts}

Plots a burst model

Description

This method produces a simple plot of the burst structure produced by the kleinberg function.

Usage

## S3 method for class 'bursts'
plot(x, ...)

Arguments

x

a data frame produced by the kleinberg function.

...

other parameters are passed along to plot.

Details

Horizontal bars represent the ‘bursts,’ with their vertical position indicating the level (i.e. intensity) and the x axis representing time. Bars appear above others to represent the hierarchical structure that emerges when long bursts contain sub-bursts of even higher activity.

Value

No return value; called to produce a plot.
