[R] Reconstructing Datasets

[Angel Lopez]

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
