`formula`	a model formula
`data`	a training data set
`cv.method`	preferably one of "boot632" (the default), "cv", or "repeatedcv".
`nfolds`	the number of bootstrap or cross-validation folds to use. defaults to 5.
`nrep`	the number of repetitions for cv.method = "repeatedcv". defaults to 4.
`folds`	a vector of pre-set cross-validation or bootstrap folds from caret::createResample or caret::createFolds.
`tunlen`	the number of values for the unknown hyperparameter to test. defaults to 10.
`crit`	the criterion by which to evaluate the model performance. must be one of "RobustMAE" (the default) or "RobustMSE".
