Extract Feature Metadata from a MultiAssayExperiment

Extracts feature-level metadata across all assays in a MultiAssayExperiment and returns a combined tibble.

Usage

pivot_feature(expomicset)

Arguments

expomicset

A MultiAssayExperiment object.

Value

A tibble with feature metadata from all assays, with an added .exp_name column.

Details

This function:

• Iterates over all assays in the MultiAssayExperiment.

• Updates each assay’s sample metadata (colData) using .update_assay_colData().

• Extracts feature-level metadata using tidybulk::pivot_transcript().

• Combines results across assays into a single tibble, adding a .exp_name column.

Examples

#' # create example data
mae <- make_example_data(
    n_samples = 10,
    return_mae = TRUE
)
#> Ensuring all omics datasets are matrices with column names.
