I am very new to R and statistics as a whole so this may be a very simple question. I am trying to carry out empirical orthogonal function (EOF) analysis of sea-level pressure (SLP) data to determine the amplitude of the North Atlantic Oscillation over time.
I have a matrix (1000,756), with 1000 years of winter mean SLP (i.e. from December to March) at 756 grid points in the North Atlantic.
How do I go about doing an EOF analysis on this data?
I have spent the last week trying to do a crash course in R but am a little tight for time so I thought I would ask! Thanks in advance for any help.
