Class: bioma.ExpressionSet
Package: bioma

Retrieve or set Expressions DataMatrix object from ExpressionSet object


ExpressionsDMObj = expressions(ESObj)
NewESObj = expressions(ESObj, NewDMObj)


ExpressionsDMObj = expressions(ESObj) returns the Expressions element (DataMatrix object), which contains expression values, from an ExpressionSet object.

NewESObj = expressions(ESObj, NewDMObj) replaces the Expressions element (DataMatrix object) in ESObj, an ExpressionSet object, with NewDMObj, a new DataMatrix object, and returns NewESObj, a new ExpressionSet object.

Input Arguments


Object of the bioma.ExpressionSet class.


Object of the DataMatrix class.

Output Arguments


DataMatrix object containing the expression values from the Expressions DataMatrix object within an ExpressionSet object.


ExpressionSet object returned after replacing the Expressions DataMatrix object.


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

% Extract expression values from Expressions DataMatrix object
ExpressionsDMObj = expressions(ESObj);
