reduce_to_mid_line = FALSE)sector.index1 |
Index for the first sector where one link end locates |
point1 |
A single value or a numeric vector of length 2. If it is a 2-elements vector, then the link would be a belt/ribbon. |
sector.index2 |
Index for the other sector where the other link end locates |
point2 |
A single value or a numeric vector of length 2. If it is a 2-elements vector, then the link would be a belt/ribbon. |
rou |
The position of the the link ends (if |
rou1 |
The position of end 1 of the link. |
rou2 |
The position of end 2 of the link. |
h |
Height of the link, measured as percent to the radius to the unit circle. By default it is automatically infered. |
h.ratio |
systematically change the link height. The value is between 0 and 1. |
w |
Since the link is a Bezier curve, it controls the shape of Bezier curve. |
h2 |
Height of the bottom edge of the link if it is a ribbon. |
w2 |
Shape of the bottom edge of the link if it is a ribbon. |
inverse |
Whether the link is inversed. |
col |
Color of the link. If the link is a ribbon, then it is the filled color for the ribbon. |
lwd |
Line (or border) width |
lty |
Line (or border) style |
border |
If the link is a ribbon, then it is the color for the ribbon border. |
directional |
0 for no direction, 1 for direction from |

Width of the arrows, pass to |

Type of the arrows, pass to |

Length of the arrows, measured in 'cm', pass to |

Color of the arrows, pass to |
arr.lwd |
Line width of arrows, pass to |
arr.lty |
Line type of arrows, pass to |

Links are implemented as quadratic Bezier curves (https://en.wikipedia.org/wiki/B%C3%A9zier_curve#Rational_B.C3.A9zier_curves ).
Drawing links does not create any track. So you can think it is independent of the tracks.
By default you only need to set sector.index1, point1, sector.index2 and point2. The
links would look nice.
