side

The side of the plot to draw the axis

at

Optional positions in user units for the tick marks.

Details

fullaxis draws a line to the edges of the plot and then calls axis to draw an axis. fullaxis is mainly useful for drawing a colored axis on a boxed plot. In order to get the tick labels the same color as the axis and ticks, pass the col.axis argument (as part of ...) as well as col. See the example for some useful tips.
