Make fancy arrows
Create and plot fancy arrows. Aspect ratio must be set to 1-1 for these arrows to plot correctly.
fancyarrows(x1, y1, x2, y2, thick = 0.08,
headlength = 0.4, headthick = 0.2, col = grey(0.5),
border = "black")x1 |
x tail coordinate |
y1 |
y tail coordinate |
x2 |
x head coordinate |
y2 |
y head coordinate |
thick |
thickness of arrow |
headlength |
length of head |
headthick |
thickness of head |
col |
fill color |
border |
color of border |
Graphical side effects.
fancyarrows only work if te aspect ratio is set to 1. See example below.

thick = 0.01; headlength = 0.2; headthick = 0.1 x = runif(10, -1, 1) y = runif(10, -1, 1) ############ MUST set asp=1 here plot(x,y, asp=1) fancyarrows(rep(0, 10) , rep(0, 10) ,x, y, thick =thick , headlength = headlength, headthick =headthick)
