I have followed the code in the link below by my loadings are far too small
(For example, the paper listed above had loading above 0.5 and below -0.5
while my loadings for PC1 go between 0.02 and -0.03).
I have standardized the data in the prcomp function so that a correlation
matrix is used in my study, just like the paper above. Does anyone have any
idea why my loadings might be so off and any suggestions regarding the PCA
functions in R to help solve this problem?
