vtreat: A Statistically Sound data.frame Processor/Conditioner

A data.frame processor/conditioner that prepares real-world data for predictive modeling in a statistically sound manner. Prepares variables so that data has fewer exceptional cases, making it easier to safely use models in production. Common problems 'vtreat' defends against: Inf, NA, too many categorical levels, rare categorical levels, new categorical levels (levels seen during application, but not during training). 'vtreat::prepare' should be used as you would use 'model.matrix'.
