AddBinVars2Biplot: Add suplementary binary variables to a biplot
Description
Add suplementary binary variables to a biplot of any kind
Usage
AddBinVars2Biplot(bip, Y, IncludeConst = TRUE, penalization = 0.2,
freq = NULL, tolerance = 1e-05, maxiter = 100)
Value
The biplot object with supplementary binary variables added.
Arguments
