featureNames

Class: bioma.data.ExptData
Namespace: bioma.data

Retrieve or set feature names in ExptData object

Syntax

FeatNames = featureNames(EDObj)
FeatNames = featureNames(EDObj, Subset)
NewESObj = featureNames(EDObj, Subset, NewFeatNames)


Description

FeatNames = featureNames(EDObj) returns a cell array of character vectors specifying all feature names in an ExptData object.

FeatNames = featureNames(EDObj, Subset) returns a cell array of character vectors specifying a subset the feature names in an ExptData object.

NewESObj = featureNames(EDObj, Subset, NewFeatNames) replaces the feature names specified by Subset in EDObj, an ExptData object, with NewFeatNames, and returns NewEDObj, a new ExptData object.

Input Arguments

EDObj	Object of the bioma.data.ExptData class.
Subset	One of the following to specify a subset of the feature names in an ExptData object: Character vector specifying a feature name Cell array of character vectors specifying feature names Positive integer Vector of positive integers Logical vector
NewFeatNames	New feature names for specific feature names within an ExptData object, specified by one of the following: Numeric vector Character vector or cell array of character vectors Character vector, which featureNames uses as a prefix for the feature names, with feature numbers appended to the prefix Logical true or false (default). If true, featureNames assigns unique feature names using the format Feature1, Feature2, etc. The number of feature names in NewFeatNames must equal the number of features specified by Subset.

Output Arguments

FeatNames	Cell array of character vectors specifying all or some of the feature names in an ExptData object. The feature names are the row names in the DataMatrix objects in the ExptData object.
NewEDObj	Object of the bioma.data.ExptData class, returned after replacing specific feature names.

Examples

Construct an ExptData object, and then retrieve the feature names from it:

% Import the bioma.data namespace to make constructor functions
% available
import bioma.data.*
% Create DataMatrix object from .txt file containing 
% expression values from microarray experiment
dmObj = DataMatrix('File', 'mouseExprsData.txt');
% Construct ExptData object
EDObj = ExptData(dmObj);
% Retrieve feature names
FNames = featureNames(EDObj);
