This function extracts pathway activity scores for specified pathways and merges them
with the sample annotations from a SummarizedExperiment object.
Usage
get_pathway_df(exp_data, pathway_scores, pathways)
Arguments
- exp_data
A `SummarizedExperiment` object containing sample metadata in `colData`.
- pathway_scores
A matrix or data frame with pathway scores (rows = pathways, columns = samples).
- pathways
A character vector of pathway names or identifiers to extract.
Value
A data frame containing the selected pathway scores and sample annotations.
