Hi R-community, I am doing a PCA and I need plots for different combinations of axes (e.g., PC1 vs PC3, and PC2 vs PC3) with the arrows indicating the loadings of each variables. What I need is exactly what I get using biplot (pca.object) but for other axes.
I have plotted PC2 and 3 using the scores of the cases, but I don't get the arrows proportional to the loadings of each variables on each axis. Any hints on this? Thanks, Silvia. -- View this message in context: http://www.nabble.com/plotting-other-axes-for-PCA-tp14952955p14952955.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
