txt.args |
Optional list of additional arguments passed to

txt.shift |
Optional numeric vector of length 2 specifying displacement of the text position relative to the centre of the yardstick. |
do.plot |
Logical. Whether to actually perform the plot ( |
A yardstick or scale bar is a line segment, drawn on any spatial graphics display, indicating the scale of the plot.
The argument x
should be an object of class "yardstick"
