apply_transform

vtreat pipe step, object defining transform.

dframe

not used, forces later arguments to bind by name.

optional, parallel cluster to run on.

parallelCluster

Apply first argument to second as a transform.

A 'data.frame' processor/conditioner that prepares real-world data for predictive modeling in a statistically sound manner.
'vtreat' 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, and new
categorical levels (levels seen during application, but not during training). Reference:
