Auto Zoom to Create a Dynamic Plot

Description

Replaces plot() with an interactive loop which allows user to click twice on the plot window to redraw with new limits. Press ESCAPE to finish.

Usage

autozoom(x, ..., after = NULL)

Arguments

x	Passed directly to plot()
...	Passed directly to plot()
after	An expression to be executed after each plot is drawn

Extras such as axes or legends are added using the after argument.
