corr_data

The example data for correlation analysis, which is the formal class 'SummarizedExperiment'. The data was obtained from Bowler RP et al.'s study, "Plasma Sphingolipids Associated with Chronic Obstructive Pulmonary Disease Phenotypes." Targeted mass spectrometry identified 69 distinct plasma sphingolipid species in 129 current and former smokers. This cohort was analyzed to explore the associations between plasma sphingolipids and COPD subphenotypes, including airflow obstruction, emphysema, and frequent exacerbations.
