OrdVarBiplot function

Plots an ordinal variable on the biplot

Plots an ordinal variable on the biplot from its fitted parameters

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, ...)

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.

Returns

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