[R] Note on PCA (not directly with R)

[Jeremy Miles]

See if you can track down Thurstone's box problem dataset. It comes (I
believe) on a CD with Loehlin's book 'latent variable models', but I'd
be surprised if you couldn't find it elsewhere.  Thurstone measured
boxes, and using EFA (rather than PCA, but they might be similar
enough to start off with) found that they were three dimensional.
