Issue:

How do I assign classes for samples in a DataSet?

Possible Solutions:

In many applications, the groups or "classes" of samples in a data set are critical to the modeling and/or interpretation of results. In PCA, scores plots can be quickly interpreted for clustering if samples can be labeled/colored according to class. Likewise, the SIMCA and PLS-DA methods rely on sample class information to generate models and assess results.
