why do the r functions pca and prcomp why does pca differ from princomp why do the functions prcomp and pca what r functions have a different percent of variance? why is prcomp used in the r r function what is pca and prcomp why does pca differ from prcomp r functions eigenvalues what is the value of pca why is eigenvalue different from pca when is pca and prcomp same which function do pca and prcomp use which of the following is a function for the computation of eigenvalues in r why do r functions pca and prcomp give different eigenwertes? why do the r functions pca and prcomp give different eigenvalues? what is the difference between pca and prcomp why does the r function pca differ from that used in the computation of the covariance matrix? why do the r functions pca and prcomp differ from those of the covariance matrix? why are eigenvalues different from covariance what is the eigenvalue of parcomp
