quiver: Quiver or Velocity Plot

Description

A quiver plot displays velocity vectors as arrows with components (u,v) at the points (x,y).

Usage

quiver(x, y, u, v,
           scale = 0.05, angle = 10, length = 0.1, ...)

Arguments

x, y

x,y-coordinates of start points of the arrows.

u, v

x,y-coordinates of start points.

scale

scales the length of the arrows.

angle

angle between shaft and edge of the arrows.

length

length of the arrow edges.

...

more options presented to the arrows primitive.

Value

• Opens a graph window and plots the velocity vectors.

Details

The matrices x, y, u, v must all be the same size and contain corresponding position and velocity components. However, x and y can also be vectors.
