getNestedTuneResultsOptPathDf

Get the opt.paths from each tuning step from the outer resampling.

Description

After you resampled a tuning wrapper (see makeTuneWrapper) with resample(..., extract = getTuneResult) this helper returns a data.frame with with all opt.paths combined by rbind. An additional column iter indicates to what resampling iteration the row belongs.

Usage

getNestedTuneResultsOptPathDf(r, trafo = FALSE)

Arguments

`r`	(ResampleResult) The result of resampling of a tuning wrapper.
`trafo`	(`logical(1)`) Should the units of the hyperparameter path be converted to the transformed scale? This is only necessary when trafo was used to create the `opt.path`s. Note that `opt.path`s are always stored on the untransformed scale. Default is `FALSE`.

Value

(data.frame). See above.
