DrugResponseAssay S4 class definition

`DrugResponseAssay` is a `SummarizedExperiment` subclass for storing drug response data.

Value

An object of class `DrugResponseAssay`.

Details

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

This class follows the Bioconductor `SummarizedExperiment` convention:

- rows represent treatments, drugs, or compounds - columns represent samples, models, or cell lines - `rowData()` stores treatment/compound-level metadata - `colData()` stores sample/model-level metadata - `metadata()` stores assay-level metadata such as units and provenance

Missing values are allowed because drug response matrices are often partially observed.
