VarBiplot function

Draws a variable on a biplot

Draws a continuous variable on a biplot

VarBiplot(bi1, bi2, b0 = 0, xmin = -3, xmax = 3, ymin = -3, ymax
                 = 3, label = "Point", mode = "a", CexPoint = 0.8,
                 PchPoint = 1, Color = "blue", ticks = c(-3, -2.5, -2,
                 -1.5, -1, -0.5, 0.5, 1, 1.5, 2, 2.5, 3), ticklabels =
                 round(ticks, digits = 2), tl = 0.04, ts = "Complete",
                 Position = "Angle", AddArrow=FALSE, CexScale=0.8, ...)

Arguments

• bi1: First component of the direction vector
• bi2: Second component of the direction vector
• b0: Constant for the regression adjusted biplots
• xmin: Minimum value of the x axis
• xmax: Maximum value of the x axis
• ymin: Minimum value of the y axis
• ymax: Maximum value of the y axis
• label: Label of the variable
• mode: Mode of the biplot: "p", "a", "b", "h", "ah" and "s".
• CexPoint: Size for the symbols and labels of the variables
• PchPoint: Symbols for the variable (when represented as a point)
• Color: Color for the variable
• ticks: Ticks when the variable is represented as a graded scale
• ticklabels: Labels for the ticks when the variable is represented as a graded scale
• tl: Thick length
• ts: Size of the mark in the gradedv scale
• Position: If the Position is "Angle" the label of the variable is placed using the angle of the vector
• AddArrow: Add an arrow to the representation of other modes of the biplot.
• CexScale: Sizes of the scales
• ...: Any other graphical parameters
