MultiPhasesGap {ArchaeoPhases} R Documentation

## Gap or hiatus between a succession of groups (for groups in temporal order constraint)

### Description

Finds, if it exists, a gap or hiatus between two successive groups. This gap or hiatus is the longest interval that satisfies P(Phase1Max < IntervalInf < IntervalSup < Phase2Min | M) = level

### Usage

MultiPhasesGap(
data,
position_minimum,
position_maximum = position_minimum + 1,
level = 0.95
)


### Arguments

 data Data frame containing the output of the MCMC algorithm. position_minimum Numeric vector containing the column number corresponding to the minimum of the events included in each group. position_maximum Numeric vector containing the column number corresponding to the end of the phases set in the same order as in position_minimum. level Probability corresponding to the level of confidence.

### 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 groups. The result is given in calendar years (BC/AD).

### Examples

  # Data extracted from ChronoModel software
data(Phases)
# List of the name of the groups
names(Phases)
# Stipulating position_maximum
MultiPhasesGap(Phases, position_minimum = c(4, 2), position_maximum = c(5, 3))
# In this case, equivalent to
MultiPhasesGap(Phases, position_minimum = c(4, 2))
