Describe an ordered group in CQL

Description

The CQL command Sequence is used to describe an ordered group of events in a model. Specific types of sequence, i.e. D_Sequence, P_Sequence, U_Sequence, and V_Sequence, are not yet implemented in stratigraphr.

Usage

cql_sequence(name, cql, boundaries = FALSE)

cql_d_sequence()

cql_p_sequence()

cql_u_sequence()

cql_v_sequence()

Arguments

name	Character. Label for the sequence.
cql	Vector of cql objects contained in the sequence.
boundaries	Logical. If TRUE, adds Boundary constraints between each item in the sequence.

Details

OxCal expects events within sequences to be in chronological order (oldest to youngest) not stratigraphic order (youngest to oldest).

Value

A cql object.
