sampleNames

Retrieve or set sample names in MetaData object

Syntax

SamFeatNames = sampleNames(MDObj) SamFeatNames = sampleNames(MDObj, Subset) NewMDObj = sampleNames(MDObj, Subset, NewSamFeatNames)

Description

SamFeatNames = sampleNames(MDObj) returns a cell array of character vectors specifying all sample names in a MetaData object.

SamFeatNames = sampleNames(MDObj, Subset) returns a cell array of character vectors specifying a subset the sample names in a MetaData object.

NewMDObj = sampleNames(MDObj, Subset, NewSamFeatNames) replaces the sample names specified by Subset in MDObj, a MetaData object, with NewSamFeatNames, and returns NewMDObj, a new MetaData object.

Input Arguments

MDObj

Object of the bioma.data.MetaData class.

Subset

One of the following to specify a subset of the sample names in a MetaData object:

Character vector specifying a sample name
Cell array of character vectors specifying sample names
Positive integer
Vector of positive integers
Logical vector

NewSamFeatNames

New sample names for specific names within a MetaData object, specified by one of the following:

Numeric vector
Cell array of character vectors or character array
Character vector which sampleNames uses as a prefix for the sample or feature names, with numbers appended to the prefix
Logical true or false (default). If true, sampleNames assigns unique names using the format Sample1, Sample2, etc.

The number of names in NewSamFeatNames must equal the number of samples specified by Subset.

Output Arguments

`SamFeatNames`	Cell array of character vectors specifying all or some of the sample names in a MetaData object. The sample names are also the row names of the `VarValues` dataset array in the MetaData object.
`NewMDObj`	Object of the `bioma.data.MetaData` class, returned after replacing specific sample names.

Examples

Construct a MetaData object, and then retrieve the sample names from it:

% Import the bioma.data namespace to make constructor function
% available
import bioma.data.*
% Construct MetaData object from .txt file
MDObj2 = MetaData('File', 'mouseSampleData.txt', 'VarDescChar', '#');
% Retrieve the sample names
SNames = sampleNames(MDObj2)
