Place a Break Mark on an Axis

Description

Places a break mark on an axis on an existing plot.

Usage

 AxisBreak(axis = 1, breakpos = NULL, pos = NA, bgcol = "white", 
           breakcol = "black", style = "slash", brw = 0.02)

Arguments

axis	which axis to break.
breakpos	where to place the break in user units.
pos	position of the axis (see axis).
bgcol	the color of the plot background.
breakcol	the color of the "break" marker.
style	Either ‘⁠gap⁠’, ‘⁠slash⁠’ or ‘⁠zigzag⁠’.
brw	break width relative to plot width.

Details

The ‘⁠pos⁠’ argument is not needed unless the user has specified a different position from the default for the axis to be broken.

Note

There is some controversy about the propriety of using discontinuous coordinates for plotting, and thus axis breaks. Discontinuous coordinates allow widely separated groups of values or outliers to appear without devoting too much of the plot to empty space.
The major objection seems to be that the reader will be misled by assuming continuous coordinates. The ‘⁠gap⁠’ style that clearly separates the two sections of the plot is probably best for avoiding this.
