`vec2distm`

converts a vector to a distance matrix.

`vec2dist`

converts a vector to a `dist`

structure.

`lower2upper.tri.inds`

is the same as `lower.to.upper.tri.inds`

from package cluster. It computes an index vector for extracting or reordering a lower
triangular matrix that is stored as a contiguous vectors.

`diag.off`

returns a vector of off-diagonal elements of a matrix.
`off`

specifies the distance above the main (0) diagonal.

`clus2memship`

converts a list whose ith element contains the indices
of objects in the ith cluster into a vector whose ith
element gives the cluster number of the ith object.

`memship2clus`

converts a vector whose ith
element gives the cluster number of the ith object into a list
whose ith element contains the indices
of objects in the ith cluster.

`vec` |
is a vector. |

`n` |
is an integer > 1. |

`m` |

`clusters` |
is a list whose ith element contains the indices of the objects belonging to the ith cluster. |

`off` |
is an integer specifying the distance above the main (0) diagonal. |

`memship` |
is a vector whose ith element gives the cluster number of the ith object. |
