Dear all, I am trying to find the PCs of a spatial data set (single variable). I want to calculate the PCs at each Lat-Lon location.
The* 'princomp'* command gives the approximate standardized data (i.e* pca$scores*), stranded deviation ..etc. I tried* 'pca$loadings'*also, but it giving value 1 all time. Then I tried manually(without using* princomb* command), and found PCs but this value is different from *'pca$loadings'*. But I can find the approximate standardized data, which is similar to *pca$scores*. But this method is time consuming. Please help me to tackle this problem. Thank you for all in advance -- DILEEPKUMAR.
