`v` |
Vector of speeds |

`p` |
Vector of probabilities |

`tr` |
The trajectory object |

`time` |
Vector of times |

`time.scale` |
The length of the intervals over which to report the speed or direction |

The speed at a time *t* is defined as the absolute value of the `velocity`

over the time interval *[t-time.scale/2, t+time.scale/2]*.

`speed`

and `mu.speed`

return a matrix indexed by the ID in the trajectory and time.
`dspeed`

, `pspeed`

and `qspeed`

return an array indexed by ID, the requested speed or probability and time.
