Cohen's D — cohens

Computes Cohen's D for each feature. If time and ID are supplied, change between two time points is computed for each subject, and Cohen's d is computed from the changes.

Usage

cohens_d(object, group, id = NULL, time = NULL, assay.type = NULL)

Arguments

object: a SummarizedExperiment or MetaboSet object
group: character, name of the group column
id: character, name of the subject ID column
time: character, name of the time column
assay.type: character, assay to be used in case of multiple assays

Value

A data frame with Cohen's d for each feature.

Examples

data(example_set)
d_results <- cohens_d(drop_qcs(example_set), group = "Group")
#> INFO [2025-06-23 22:36:28] Starting to compute Cohen's D between groups B & A
#> INFO [2025-06-23 22:36:28] Cohen's D computed.
d_results_time <- cohens_d(drop_qcs(example_set),
  group = "Group", time = "Time", id = "Subject_ID"
)
#> INFO [2025-06-23 22:36:28] Starting to compute Cohen's D between groups B & A from time change 2 - 1
#> INFO [2025-06-23 22:36:28] Cohen's D computed.
