# Finding representative sets by group and their quality statistics.

### Description

This function determines representative sequences by group and returns the representatives by group and/or the quality statistics of the representative sets. The function is a wrapper for the TraMineR `seqrep`

function.

### Usage

1 |

### Arguments

`seqdata` |
state sequence object as defined by |

`group` |
group variable. If |

`mdis` |
dissimilarity matrix. If |

`ret` |
What should be returned? One of |

`...` |
additional arguments passed to |

### Details

The function is a wrapper for running `seqrep`

on the different groups defined by the `group`

variable.

### Value

If `ret="stat"`

, a list with the quality statistics for the set of representatives of each group.

If `ret="rep"`

, a list with the set of representatives of each group.

If `ret="both"`

, a list with the two previous outcomes.

### Note

This function is a pre-release and further testing is still needed, please report any problems.
