[R] Mental Block with PCA of multivariate time series!

Please could someone point me in the right direction as I appear to be having a total mental block with fairly basic PCA problem!

I have a large dataframe where rows represent independent observations and columns are variables. I am wanting to perform PCA sequentially on blocks of nrows at a time and produce a graphical output of the loadings for the first 2 EOFs for each variable.

I'm sure I've performed a very similar routine in the past, but the method is currently escaping me.

Any help gratefully received!
