NominalLogisticBiplot (version 0.2)

plot.nominal.logistic.biplot: Graphical representation of a Nominal Logistic Biplot.

Description

Plotting a Nominal Logistic Biplot. There are parameters related to the way in which the biplot is plotted. All the posible parameters have default values

Arguments

x

An object of the class nominal.logistic.biplot.

planex

Dimension for X axis.

planey

Dimension for Y axis.

QuitNotPredicted

Should the non-predicted categories be represented on the graph?

ReestimateInFocusPlane

Shuld the item parameters be reestimated using only the dimensiona of the plot.? If FALSE the values of the parameters for other dimensions are set to 0. Default is FALSE

proofMode

Should each variable be plotted on a separate plot? If FALSE, a single plot with a legend for identifying each variable is made.

AtLeastR2

It establishes the cutting value to plot a variable attending to its Nagelkerke R^2 value. A variable is plotted if its R^2 is higher than this value.

xlimi

Minimum value on the x-axis.

xlimu

Maximum value on the x-axis.

ylimi

Minimum value on the y-axis.

ylimu

Maximum value on the y-axis.

linesVoronoi

Should the tesselation be plotted.? Default is FALSE and only the category points are plotted for a better reading of the plot.

ShowAxis

Should the axis be shown?

PlotVars

Should the variables (items) be pplotted?

PlotInd

Should the individuals be plotted?

LabelVar

Should the variable labels be shown?

LabelInd

Should the individual labels be shown?

CexInd

Size of the individual points. It can be an array with the cex information for each row.

CexVar

Size of the category points. It can be an array with the cex information for each variable.

ColorInd

Color of the individual points. It can be an array with the color information for each row.

ColorVar

Color for the variables. It can be an array with the color information for each variable.

SmartLabels

Should the text labels be printed accordind to its position on the plot?.

PchInd

Symbol for the individuals. It can be an array with the pch information for each row.

PchVar

Symbol for the variables. It could be an array with the pch information for each variable.

LabelValuesVar

List with the text labels for all the variables. If NULL, initial labels are used.

ShowResults

Should the results of the proccess of calculating the prediction regions be shown?

...

Additional parameters to plot.

Details

The function without parameters plots the nominal.logistic.biplot object with labels in the original data and default values for colors, symbols and sizes for points and lines. Other values of colors, symbols and sizes can be supplied. A single value applies to all the points but an array with different values can be used to improve the undestanding of the plot.-
