PCA is a very popular method of dimensionality reduction because it provides a way to easily reduce the dimensions and is easy to understand. For this reason, PCA has been used in various applications from image compression to complex gene comparison. While using PCA, one should keep in mind ...

While implementing the cosine stuff, I realized it was basically the same calculation as covariance and (pearson) correlation, which I had already done in thepcapack package. So I tossed those in as well and put it all under one interface. My enthusiasm for this problem also nicely explains ...
