R: Quiver or Velocity Plot

quiver {pracma} | R Documentation

## 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.

### 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.

### Value

Opens a graph window and plots the velocity vectors.
