Update the state of first argument to have learned or fit from second argument, and compute a cross validated example of such a transform.

fit_prepare(vps, dframe, ..., weights = NULL, parallelCluster = NULL)

Arguments

vps

vtreat pipe step, object specifying fit.

dframe

data.frame, data to fit from.

...

not used, forces later arguments to bind by name.

weights

optional, per-dframe data weights.

parallelCluster

optional, parallel cluster to run on.

Value

@return named list containing: treatments and cross_frame

Details

Note: input vps is not altered, fit is in returned list.
