plot.tunelocal: Graphical display resulting from tunelocal

Description

The function plot.tunelocal allows the analyst to graphically display the optimal model dimension using a convex hull.

Usage

# S3 method for tunelocal
plot(x,...)

Value

Graphical displays of a convex hull computed using the original data and the bootstrapped data when in tunelocal the input parameter boot=TRUE computed bootstrapped data too.

Arguments

x

The results of the function tunelocal. It shows the models that are located on the boundary of the convex hull and selects an optimal model by means of the scree test values (st). When using boots=F, it gives the set of possible dimension combination of the original data using only the original data array. When using boots=T, it gives the set of possible dimension combination of the original data using bootstrapped data arrays.

...

Further arguments passed to or from other methods.
