getNestedTuneResultsOptPathDf {mlr} | R Documentation

## Get the `opt.path`s 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.path`s 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.
