## Draw Labeled Vectors in 2D or 3D

### Description

Graphics utility functions to draw vectors from an origin to a collection of
points (using `arrows`

in 2D or
`lines3d`

in 3D) with labels for each (using
`text`

or `texts3d`

).

### Usage

```
vectors(
x,
origin = c(0, 0),
labels = rownames(x),
scale = 1,
col = "blue",
lwd = 1,
cex = 1,
length = 0.1,
angle = 13,
pos = NULL,
...
)
```

### Arguments

`x` |
A two-column matrix or a three-column matrix containing the end points of the vectors |

`origin` |
Starting point(s) for the vectors |

`labels` |
Labels for the vectors |

`scale` |
A multiplier for the length of each vector |

`col` |
color(s) for the vectors. |

`lwd` |
line width(s) for the vectors. |

`cex` |
color(s) for the vectors. |

`length` |
For |

`angle` |
For |

`pos` |
For |

`...` |
other graphical parameters, such as |

### Details

The graphical parameters `col`

, `lty`

and `lwd`

can be
vectors of length greater than one and will be recycled if necessary

### Value

None

### Examples

```
plot(c(-3, 3), c(-3,3), type="n")
X <- matrix(rnorm(10), ncol=2)
rownames(X) <- LETTERS[1:5]
vectors(X, scale=2, col=palette())
```
