BERT: Hierarchical Batch-Effect Adjustment with Trees

Provides efficient batch-effect adjustment of data with missing values. BERT orders all batch effect correction to a tree of pairwise computations. BERT allows parallelization over sub-trees.

Adjust two batches to each other.	adjust_node
Adjust a hierarchy level sequentially.	adjustment_step
Adjust data using the BERT algorithm.	BERT
Chunks data into n segments with (close-to) equivalent number of batches and stores them in temporary RDS files	chunk_data
Compute the average silhouette width (ASW) for the dataset with respect to both label and batch.	compute_asw
Count the number of numeric features in this dataset. Columns labeled "Batch", "Sample" or "Label" will be ignored.	count_existing
Format the data as expected by BERT.	format_DF
Generate dataset with batch-effects and 2 classes with a specified imbalance.	generate_data_covariables
Generate dataset with batch-effects and biological labels using a simple LS model	generate_dataset
Check, which features contain enough numeric data to be adjusted (at least 2 numeric values)	get_adjustable_features
Check, which features contain enough numeric data to be adjusted (at least 2 numeric values per batch and covariate level)	get_adjustable_features_with_mod
Identifies the adjustable features using only the references. Similar to the function in adjust_features.R but with different arguments	identify_adjustableFeatures_refs
Identifies the references to use for this specific batch effect adjustment	identify_references
Ordinal encoding of a vector.	ordinal_encode
Adjusts all chunks of data (in parallel) as far as possible.	parallel_bert
A method to remove batch effects estimated from a subset (references) per batch only. Source code is heavily based on limma::removeBatchEffects by Gordon Smyth and Carolyn de Graaf	removeBatchEffectRefs
Replaces missing values (NaN) by NA, this appears to be faster	replace_missing
Strip column labelled Cov_1 from dataframe.	strip_Covariable
Verifies that the input to BERT is valid.	validate_bert_input
Validate the user input to the function generate_dataset. Raises an error if and only if the input is malformatted.	validate_input_generate_dataset
Verify that the Reference column of the data contains only zeros and ones (if it is present at all)	verify_references
