ExpressionAssay S4 class definition

`ExpressionAssay` is a `SummarizedExperiment` subclass for storing gene or transcript expression data.

Value

An object of class `ExpressionAssay`.

Details

The primary assay is named `"expression"` and should contain a numeric matrix-like object with features as rows and samples/models as columns.

This class follows the Bioconductor `SummarizedExperiment` convention:

- rows represent features, such as genes or transcripts - columns represent samples, models, or cell lines - `rowData()` stores feature-level metadata - `colData()` stores sample/model-level metadata - `metadata()` stores assay-level metadata such as units and provenance
