getObjf

mlrTools
This function receives a configuration for a tuning experiment,
and returns an objective function to be tuned via SPOT.
It basically provides the result from a call to <code>resample</code>:
<code>resample(lrn, task, resample, measures = measures, show.info = FALSE)</code>,
with measures defined as <code>mmce</code> for classification and <code>rmse</code> for regression, <code>timeboth</code>, <code>timetrain</code>, and
<code>timepredict</code>.

Implements additional models, simulation tools, and interfaces as extensions to 'SPOT'.
It provides tools for hyperparameter tuning via 'keras/tensorflow', interfacing 'mlr', for performing Markov chain simulations,
and for sensitivity analysis based on sequential bifurcation methods as described in Bettonvil and Kleijnen (1996).
Furthermore, additional plotting functions for output from 'SPOT' runs are implemented.
