getNestedTuneResultsOptPathDf

[<code><a rd-options="" href="/link/ResampleResult?package=mlr&version=2.8" data-mini-rdoc="mlr::ResampleResult">ResampleResult</a></code>] 
The result of resampling of a tuning wrapper.


After you resampled a tuning wrapper (see <code><a rd-options="" href="/link/makeTuneWrapper?package=mlr&version=2.8" data-mini-rdoc="mlr::makeTuneWrapper">makeTuneWrapper</a></code>)
with <code>resample(..., extract = getTuneResult)</code> this helper returns a <code>data.frame</code> with
with all <code>opt.path</code>s combined by <code>rbind</code>.
An additional column <code>iter</code> indicates to what resampling iteration the row belongs.


Interface to a large number of classification and regression
techniques, including machine-readable parameter descriptions. There is
also an experimental extension for survival analysis, clustering and
general, example-specific cost-sensitive learning. Generic resampling,
including cross-validation, bootstrapping and subsampling. Hyperparameter
tuning with modern optimization techniques, for single- and multi-objective
problems. Filter and wrapper methods for feature selection. Extension of
basic learners with additional operations common in machine learning, also
allowing for easy nested resampling. Most operations can be parallelized.

getNestedTuneResultsOptPathDf: Get the `opt.path`s from each tuning step from the outer resampling.
