# Repair a LoCoH-xy object

### Description

Recreates a LoCoH-xy object

### Usage

1 2 | ```
lxy.repair(lxy, fix.dup.ptid = FALSE, dt.int.round.to = 0.1,
tau.diff.max = 0.02)
``` |

### Arguments

`lxy` |
A LoCoH-xy object |

`fix.dup.ptid` |
Generate new ptid value(s) if there are any duplicates |

`dt.int.round.to` |
The proportion of the median sampling frequency that time intervals will be rounded to when computing the frequency table of sampling intervals (no change is made to the time stamps) |

`tau.diff.max` |
The maximum deviation from tau (the median delta.t of the entire dataset), expressed as a proportion of tau, that time difference between two points must fall for the distance between those two points to be included in the calculation of the median step length |

### Details

This will return a new lxy object containing the original xys, dt, and ptid from lxy. All other items and attributes (including the comment) will be recreated or set to NULL

Set `fix.dup.ptid=TRUE`

to automatically generate new ptid values if any duplcates are detected. If `fix.dup.ptid=FALSE`

and duplicate ptid values are detected, an error message will result.

`tau.diff.max`

exists to eliminate the inclusion of temporal outliers in the computation of the median step length. The time difference betwen points must be withint `tau.diff.max`

of tau for that pair of points to be included in step length calculation.

### Value

A LoCoH-xy object
