permutation_test_model: Permutation test

In sipss/AlpsLCMS: Signal processing of LC-MS metabolomics

Description

Make permutations with data and default settings from an lcms_data_analysis_method

Usage

permutation_test_model(
  dataset,
  y_column,
  identity_column,
  balance_in_train = NULL,
  external_val,
  internal_val,
  data_analysis_method,
  nPerm = 50
)

Arguments

dataset	An lcms_dataset_family object
y_column	A string with the name of the y column (present in the metadata of the dataset)
identity_column	NULL or a string with the name of the identity column (present in the metadata of the dataset).
external_val	A list with two elements: iterations and test_size. See random_subsampling for further details
internal_val	A list with two elements: iterations and test_size. See random_subsampling for further details
data_analysis_method	An lcms_data_analysis_method object
nPerm	number of permutations

Value
