Add Arrows to a Circular Plot
Description
Draw arrows in a circular plot.
Usage
arrows.circular(x, y = NULL, x0 = 0, y0 = 0, na.rm = FALSE,
shrink = 1, plot.info = NULL, zero = NULL, rotation = NULL, ...)
Arguments
x |
a vector. The object is coerced to class circular .
|
y |
a vector with the same length as x .
|
x0 |
a vector of origins (x axis).
|
y0 |
a vector of origins (y axis).
|
na.rm |
logical, indicating if NA 's should be omitted.
|
shrink |
parameter that controls the size of the plotted circle.
Default is 1. Larger values shrink the circle, while smaller values
enlarge the circle.
|
plot.info |
an object from plot.circular that
contains information on the zero , the rotation and next.points .
|
zero |
the zero used in the plot. Ignored if plot.info is provided.
|
rotation |
the rotation used in the plot. Ignored if plot.info is provided.
|
... |
futher parameters passed to arrows .
|
Note
The function call arrows and it is not a method of arrows .
