plotloads

Purpose

Extract and display loadings information from model.

Synopsis

a = plotloads(modl,options)

a = plotloads(loads,labels,classes)

options = plotloads('options')

Description

Given a standard model structure, relevant loading information (e.g. labels) is collected and passed to PLOTGUI for plotting. The input is the model containing loadings to plot modl. (e.g. see MODELSTRUCT). Optional input options is discussed below.

Input loads is a N by K loadings matrix (class “double”). Optional input labels is a character or cell array with N rows containing sample labels, and optional input classes is a vector with N integer elements of class identifiers.

If no output is requested then PLOTLOADS initiates an interactive plotting utility to make loadings plots. If an output is requested, no plots are made, and the output a is a dataset object containing the loadings and labels, etc.

Options

             options =   a structure array with the following fields:

              display:   [ {'on'} | 'off' ], governs level of display,

                  plots:   ['none' | 'final' | {'auto'} |], governs plotting behavior, 'auto' makes plots if no output is requested {default}, and

                figure:  [],governs where plots are made, when figure = [] plots are made in a new figure window {default}, this can also be a valid figure number (i.e. figure handle).

The default options can be retreived using: options = plotloads('options');.
