run: Runs an iterator, applying the chosen model multiple times.

In structToolbox: Data processing & analysis tools for Metabolomics and other omics

Description

Running an iterator will apply the iterator a number of times to a DatasetExperiment. For example, in cross-validation the same model is applied multiple times to the same data, splitting it into training and test sets. The input metric object can be calculated and collected for each iteration as an output.

Usage

## S4 method for signature 'bootstrap,DatasetExperiment,metric'
run(I, D, MET = NULL)

## S4 method for signature 'forward_selection_by_rank,DatasetExperiment,metric'
run(I, D, MET)

## S4 method for signature 'grid_search_1d,DatasetExperiment,metric'
run(I, D, MET)

## S4 method for signature 'kfold_xval,DatasetExperiment,metric'
run(I, D, MET = NULL)

## S4 method for signature 'permutation_test,DatasetExperiment,metric'
run(I, D, MET = NULL)

## S4 method for signature 'permute_sample_order,DatasetExperiment,metric'
run(I, D, MET)

Arguments

I	an iterator object
D	a DatasetExperiment object
MET	a metric object

Value

Modified iterator object

Examples

D = iris_DatasetExperiment() # get some data
MET = metric()  # use a metric
I = example_iterator() # initialise iterator
models(I) = example_model() # set the model
I = run(I,D,MET) # run
