%description
Visual 2D point and contour plots for binary classification modeling under
algorithms such as glm(), randomForest(), gbm(), nnet() and svm(),
presented over two dimensions generated by FAMD and MCA methods. Package
'FactoMineR' for multivariate reduction functions and package 'MBA' for
interpolation functions are used. The package can be used to visualize the
discriminant power of input variables and algorithmic modeling, explore
outliers, compare algorithm behaviour, etc. It has been created initially
for teaching purposes, but it has also many practical uses.
