Function to concatenate the columns of a matrix or data frame for each row into a single character variable, which can optionally be reconverted to numeric. Called internally by `sorter`

. For example, a row of a matrix containing `c(1, 2, 3, 5)`

will be concatenated to `"1235"`

.

makePatterns(dat, times, num = TRUE, mindur = NULL, igrpt = FALSE)
``` |

`dat` |
a matrix or data frame such as |

`times` |
see |

`num` |
logical indicator, should a numeric version of the concatenate rows be return. Default is |

`mindur` |
minimum duration. If |

`igrpt` |
Option to ignore repeated values when sorting, allowing the sorting algorithm in |

`out ` |
A vector of patterns of length |
