Description

An S4 class to store the event and accumulation times of archaeological assemblages.

Slots

dates

A length-m numeric vector of dates expressed in rata die.

model

A multiple linear model: the Gaussian multiple linear regression model fitted for event date estimation and prediction.

keep

An integer vector giving the subscripts of the CA components to keep.
