featureVarValues

Class: bioma.ExpressionSet
Package: bioma

Retrieve or set feature variable data values in ExpressionSet object

Syntax

DSVarValues = featureVarValues(ESObj)
NewESObj = featureVarValues(ESObj, NewDSVarValues)

Description

DSVarValues = featureVarValues(ESObj) returns a dataset array containing the measured value of each variable per feature from the MetaData object of an ExpressionSet object.

NewESObj = featureVarValues(ESObj, NewDSVarValues) replaces the feature variable values in ESObj, an ExpressionSet object, with NewDSVarValues, and returns NewESObj, a new ExpressionSet object.

Input Arguments

ESObj

Object of the bioma.ExpressionSet class.

NewDSVarValues

A dataset array containing a value for each variable per feature. In this dataset array, the columns correspond to variables and rows correspond to feature. The row names (feature names) must match the row names (feature names) in DSVarValues, the dataset array being replaced in the MetaData object in the ExpressionSet object, ESObj.

Output Arguments

DSVarValues

A dataset array containing the measured value of each variable per feature from the MetaData object of an ExpressionSet object. In this dataset array, the columns correspond to variables and rows correspond to features.

NewESObj

Object of the bioma.ExpressionSet class, returned after replacing the dataset array containing the feature variable values.
