Reconstructing Datasets
Hi Laura, You might want to have a look at function decevf in package pastecs. It uses eigenvector filtering to reconstruct a signal using only the most representative eigenvectors. It is applied for time series but you could easily modify the code to use it for spatial data also. Bests, Angel

Hi, Is it possible to recreate "smoothed" data sets in R, by performing a PCA and then reconstructing a data set from say the first 2/3 EOFs? I've had a look in the help pages and don't seem to find anything relevant.
