OrdVarBiplot: Plots an ordinal variable on the biplot

Description

Plots an ordinal variable on the biplot from its fitted parameters

Usage

OrdVarBiplot(bi1, bi2, threshold, xmin = -3, xmax = 3, ymin = -3, 
ymax = 3, label = "Point", mode = "a", CexPoint = 0.8,
PchPoint = 1, Color = "green", tl = 0.03, textpos = 1, CexScale= 0.5, ...)

Value

Returns a graphical representation of the ordinal variable on the current plot

Arguments

bi1: Slope for the first dimension to plot
bi2: Slope for the second dimension to plot
threshold: Thresholds for each category of the variable
xmin: Minimum value of the X on the plot
xmax: Maximum value of the X on the plot
ymin: Minimum value of the Y on the plot
ymax: Maximum value of the X on the plot
label: Label of the variable
mode: Mode of the plot (as in a regular biplot)
CexPoint: Size of the point
PchPoint: Mark for the point
Color: Color
tl: Tick Length
textpos: Position of the label
CexScale: Sizes of the scales
...: Any aditional graphical parameter

Details

Plots an ordinal variable on the biplot from its fitted parameters. The plot uses the same parameters as any other biplot.
