Generate permutation matrix from ReadCountSet objects or from label vectors.

1 | ```
genpermuteMat(obj, times = 1000, seed = NULL)
``` |

`obj` |
a ReadCountSet object or a label vector. This function needs the original sample label information to generate permutation matrix. |

`times` |
an integer indication the times of permutation. |

`seed` |
an integer or NULL, to produce the random seed (an integer vector) for generating random permutation matrix: the same seed generates the same permutation matrix, which is introduced for reproducibility. |

A sample label shuffled matrix, rows corresponding to samples and columns for each permutation.
