This function calculates different dissmilarity/distance indices of sequences.

1 2 3 | ```
sequences.distance(sequences = NULL, groups = NULL,
method = c("levenshtein", "cosine", "q-gram", "jaccard", "ja-wi",
"dam-le", "hamming", "osa", "lcs"), divLength = FALSE)
``` |

`sequences` |
Vector containing sequences |

`groups` |
Vector containing names of different samples (if present) |

`method` |
Dissmilariy method (see details) |

`divLength` |
Divide sequences into subsets of the same sequence length? (default: FALSE) |

This function calculates dissmiliarity/distance indices based on sequences. Levenshtein, cosine, q-gram, Jaccard, Jaro-Winker (`ja-wi`

), Damerau-Levenshtein (`dam-le`

), Hamming, Optimal string alignment (`osa`

) and longest common substring (`lcs`

) distance can be chosen. For details see `stringdist-metrics`

.

Output is a distance matrix containing dissimilarity indices/distances between sequences.
