Researchers have developed msPCA, a new open-source R package designed for sparse principal component analysis that can handle multiple components. The package utilizes an alternating maximization algorithm to produce sparse loading vectors that effectively explain dataset variance while maintaining non-redundancy through either orthogonal loading vectors or zero pairwise correlation between principal components. Benchmarks indicate msPCA can efficiently process datasets with thousands of features, delivering competitive performance and high variance explanation with controlled feasibility. AI
