strat.var: Compute the realtive thickness variations of sections

In StratigrapheR: Integrated Stratigraphy

Compute the realtive thickness variations of sections

Description

Based on tie-points, this function computes the relative thickness variations of different sections compared to a reference section or composite sections

Usage

strat.var(dt, initial = NULL, ref = 1, events = NULL, sections = NULL)

Arguments

dt	a matrix of depth (or time) of the different tie points. Columns are for the sections, rows for each tie point. No NA values are accepted, if necessary, tie-points have to be estimated, using for instance the strat.mean function
initial	which tie-points are originally present in the sections (if NULL, by default all the values are considered as originally present)
ref	the column index for the section which acts as a reference (by default, it is set to 1, for the first columns)
events	the name of the tie points
sections	the name of the sections

Examples

dt     <- tie.points.example[,2:6]
events <- tie.points.example[,1]

extended <- strat.mean(dt = dt, events = events)

strat.var(extended$dt, extended$initial)
