Compress clusters of features to a single feature

Source: R/feature_clustering.R
compress_clusters.Rd

This function compresses clusters found by cluster_features, keeping only the feature with the highest median peak area. The features that were discarded are recorded in feature data, under Cluster_features.

Usage

compress_clusters(object)

Arguments

object

a SummarizedExperiment or MetaboSet object

Value

A SummarizedExperiment or MetaboSet object with only one feature per cluster.
