Dear All, I want to use princomp() function in R in order to calculate
Principle Component Analysis.In different papers, I have seen "PCA 1", "PCA
2", "PCA 11" , etc. Would you please tell me how can i calculate different
PCAs in R?At the moment i just use this line "eigenVectors <-
pca$loadings"But I don?t know if it is correct to use loadings.Thank you in
advance. Best regards,
