I am currently working with foraminiferous fauna data for mixing layer reconstruction over the past 20ka. We did the reconstruction from the abundance of some species, which represent deeper or shallower mixing layer and built a curve (from a GAM analysis), which showed this variation.
Now we want to find patterns of time series and space within that data. In the article "Late Quaternary coccolith Records in the South China Sea and East Asian Monsoon Dynamics" (2013) - http://www.sciencedirect.com/science/article/pii/S0921818113001872 - the authors used an EOF analysis with the same objective, however, they did with a statistical program called PAST, which does not have the EOF function, but this was done from a PCA.
I would like to know how this EOF analysis can be done from a PCA (what data to use and how to organize, for example) or how to perform EOF analysis in R from the Spacetime package (or Clim.Pact) with the same Past questions, about what data to use and how to organizelos."
If anyone can shed a light!
Hi Giggia, welcome to Sopt! Your question is somewhat outside the scope of programming, as it has a focus on statistics, so it may be more difficult to get an answer around here. To make it a little easier, I suggest that you post an example of data that can be used in the analysis. It is worth also asking the question on Crossvalidated (in English), where you will surely find more statistics to help you than here.

Thank you very much. Let’s write there!
