[R] eof and svd calculus with NA's

Im currently dealing with large datasets of some climatic parameters and I'm
performing some EOF analysis on them. The problem is that for one of the
datasets, the continents are labelled as NA's (since the data was gathered
over the oceans). I don't know to which extent the dropping of those NA's
from the matrix will affect the future calculus, and how to maintain the
geographic entity of the EOF's

Thanks in advance
