Computes representative normalized RAD of a group of normalized RADs.

1 2 | ```
representative_RAD(norm_rad, sample_ids = NULL, plot = F, min_rank = 1,
confidence = 0.95, with_conf = TRUE, ...)
``` |

`norm_rad` |
A matrix which contains the normalized RADs (samples in rows). |

`sample_ids` |
Vector of row numbers of the desired group, from which a representative RAD is going to be produced. |

`plot` |
A logical. If |

`min_rank` |
The minimum rank to be considered for making repRADs. |

`confidence` |
Confidence interval of plotted repRAD. Default is 0.9. |

`with_conf` |
A logical. If |

`...` |
Other graphical parameters to use for plotting. This function uses internally the
functions |

A list of following parameters:

$average: Contains a vector of length equal to the columns of `norm_rad`

. This in the representative normalized RAD which is
the average of normalized RAD of the group.

$population_sd: A vector of length equal to the columns of `norm_rad`

which contains the standard deviation
for each rank.

$standard_error: A vector of length equal to the columns of `norm_rad`

which contains the standard deviation
of the mean for each rank. This vector is the result of `population_sd / sqrt(n)`

,
when n is the number of members of the group (length of `sample_ids`

).

If `plot = TRUE`

, plot of the repRAD is produced and would be added to the previous plot.

If `with_conf = TRUE`

, confidence interval would be added to the repRAD plot.

`RADnormalization`

for normalize an abundance vector. This function return more details compared to `RADnormalization_matrix`

,
`RADnormalization_matrix`

for normalize an entire otutable,
`representative_point`

for study the representative of groups of samples in a multi-dimensional scaling plot,
