Reference to the feature names in getExplainedVariance #25

Hello,

When using new PCA(dataset[]), regardless the order of my observations, (for instance dataset = [[1, 2], [100, 2000]] or dataset = [[2, 1], [2000,100]], the method getExplainedVariance always seems to returnthe same array of values. if there a way to know the reference of the column/feature the score refers to ?

Thank you!

The explained variance is related to the principal components, not the original features.
