Calculate pairwise comparisons using Quade's post-hoc test for
unreplicated blocked data. This test is usually conducted post-hoc after significant results of the omnibus test, `quade.test`

.

posthoc.quade.test(y, ...)
## Default S3 method:
posthoc.quade.test(y, groups, blocks, dist =
c("TDist", "Normal"), p.adjust.method = p.adjust.methods, ...)
``` |

`y` |
either a numeric vector of data values, or a data matrix. |

`groups` |
a vector giving the group for the corresponding elements of |

`blocks` |
a vector giving the block for the corresponding elements
of |

`dist` |
the method for determining the p-value. The default distribution is |

`p.adjust.method` |
Method for adjusting p values
(see |

`...` |
further arguments to be passed to or from methods. |

A one-way ANOVA with repeated measures that is also referred to as ANOVA with unreplicated block design can also be conducted via the `quade.test`

. The consequent post-hoc pairwise multiple comparison test according to Quade is conducted with this function.

If *y* is a matrix, than the columns refer to the treatment and the rows indicate the block.

See `vignette("PMCMR")`

for details.
