elementData

Class: bioma.ExpressionSet
Namespace: bioma

Retrieve or set data element (DataMatrix object) in ExpressionSet object

Syntax

DMObj = elementData(ESObj, Element) NewESObj = elementData(ESObj, Element, NewDMObj)

Description

DMObj = elementData(ESObj, Element) returns the DataMatrix object from an ExpressionSet object, specified by Element, a positive integer or a character vector specifying an element name.

NewESObj = elementData(ESObj, Element, NewDMObj) replaces the DataMatrix object specified by Element in ESObj, an ExpressionSet object, with NewDMObj, a new DataMatrix object, and returns NewESObj, a new ExpressionSet object.

Input Arguments

`ESObj`	Object of the `bioma.ExpressionSet` class.
`Element`	Element (DataMatrix object) in an ExpressionSet object, specified by either of the following: Positive integer Character vector specifying the element name
`NewDMObj`	Object of the DataMatrix class. The sample names and feature names in `NewDMObj` must match the sample names and feature names in the DataMatrix object specified by `Element`.

Output Arguments

`DMObj`	Object of the DataMatrix class, returned from the ExptData object of an ExpressionSet object.
`NewESObj`	Object of the `bioma.ExpressionSet` class, returned after replacing a specified data element (DataMatrix object).

Examples

Construct an ExpressionSet object, ESObj, as described in the Examples section of the bioma.ExpressionSet class reference page. Extract a DataMatrix object from it:

% Extract first DataMatrix object
ExtractedDMObj = elementData(ESObj, 1);
