sigplot {hdeco}R Documentation

A HDECO internal plot tool for identifying G-squared significances on spectra.

Description

Adds shaded points to decomposition spectra to identify decomposition steps with significant G-squared2 statistic values. Requires the output from t.hdeco, specifically the object titled .HPROFIL. This function is called internally by t.hdeco, but can be used independently if the .HPROFIL object exists.

Usage

sigplot(mat = .HPROFIL, column = 5, sigcol = 7, tit = "Title of Graph", xtit = "Step", ytit = "Uncertainty Coefficient", override = FALSE, lowy = 0, highy = 1)

Arguments

mat The required .HPROFIL matrix output by the t.hdeco function (or a comparable matrix object).
column Identifies the column (integer) with the data to be plotted (e.g., 5 is the uncertainty coefficient - UNC).
sigcol Identifies the column (integer) with the significance value for the G-squared statistic.
tit A text string identifying the title for the plot.
xtit A text string used for the x-axis label.
ytit A text string used for the y-axis label.
override Boolean flag to override the minimum and maximum y-axis values.
lowy If override is TRUE, then the new low y-axis value.
highy If override is TRUE, then the new high y-axis value.

Value

The graphical result is provided in the graphics window.
