Hi,

I have performed a PCA and am trying to graphically represent a few retained PCs using a technique proposed by Ramsay and Silverman (Functional Data Analysis with R and Matlab, 2009). I do not have the cd for the source code. Has anyone tried to plot +/- curves of adding (+) and subtracting (-) a multiple of each principal component curve? If so, would you be willing to pass it along?

Thanks,

Eric
