# MultiPhasesGap: Gap/Hiatus between a succession of phases (for phases in... In RChronoModel: Post-Processing of the Markov Chain Simulated by ChronoModel or Oxcal

## Description

This function finds, if it exists, the gap between two successive phases. This gap or hiatus is the longest interval [IntervalInf, IntervalSup] that satisfies : P(Phase1Max < IntervalInf < IntervalSup < Phase2Min | M) = level for each successive phase.

## Usage

 ```1 2``` ```MultiPhasesGap(data, position_minimum, position_maximum = position_minimum+1, level = 0.95, max_decimal = 0) ```

## Arguments

 `data` dataframe containing the output of the MCMC algorithm `position_minimum` numeric vector containing the column number corresponding to the minimum of the dates included in each phase `position_maximum` numeric vector containing the column number corresponding to the maximum of the dates included in each phase. By default, position_maximum = position_minimum + 1. `level` probability corresponding to the level of confidence `max_decimal` maximum number of decimal

## Details

For each i, MultiPhasesGap computes the gap interval for the phase defined by its minimum position_minimum[i] and its maximum position_maximum[i]. The default value of position_maximum corresponds to CSV files exported from ChronoModel software.

## Value

Returns a matrix of values containing the level of confidence and the endpoints of the gap for each pair of successive phases
