marrayDead | R Documentation |

Converts dead-recovery capture histories to an m-array.

marrayDead(MR, freq = 1, groups = NULL)

`MR` |
an individuals x time matrix with 1 denoting either the time of marking or the time of recovery; otherwise 0. |

`freq` |
a vector with the number of animals with each capture history, or a matrix with a column for each group. If a single value is supplied, it will be used for all rows in the capture history; the default is to assume each row corresponds to a single animal. |

`groups` |
a factor (or a vector that can be coerced to a factor) which identifies the group that each row of |

The argument `MR`

can be a matrix of unique capture histories accompanied by a vector or matrix, `freq`

, specifying the number of animals with each capture history. For other formats, see `ch2matrix`

.

An m-array, a (years-1) x years x groups array, where element [i, j, g] contains the number of individuals in group g marked in year i and recovered in year j+1. The last column contains the number of individuals marked in year i and never recovered. If no groups are specified, this will be a (years-1) x years matrix.
