## Retrieve expression data from eSets.

### Description

These generic functions access the expression and error measurements of assay data stored in an object derived from the `eSet-class` or `exprSet-class`.

    exprs(object)
    exprs(object) <- value
    se.exprs(object)
    se.exprs(object) <- value

### Arguments

`object` | Object derived from class `eSet`, or `exprSet`
`value` | Matrix with rows representing features and columns samples.
