boundaries {ArchaeoPhases}

Phase Time Range

Description

Computes the shortest interval that satisfies P(PhaseMin < IntervalInf < IntervalSup < PhaseMax | M) = level for each phase.

Usage

boundaries(x, y, ...)

## S4 method for signature 'numeric,numeric'
boundaries(x, y, level = 0.95)

## S4 method for signature 'PhasesMCMC,missing'
boundaries(x, level = 0.95)

Arguments

x, y

A numeric vector. If y is missing, x must be an PhasesMCMC object.

...

Currently not used.

level

A length-one numeric vector giving the confidence level.

Value

The endpoints of the shortest time range (at a given level).

Methods (by class)

• boundaries(x = numeric, y = numeric): Returns a length-two numeric vector (terminal times).

• boundaries(x = PhasesMCMC, y = missing): Returns a TimeRange object.
