PCA and gglot2

Wed, Jul 10, 2013 9:49 AM

Perhaps the post at
http://www.codesofmylife.com/2012/06/07/plotting-pca-results-with-ggplot2/

would help?
 
(as would googling "biplot in ggplot2", which is how I found it...)

Incidentally, if you want base graphics biplots with points and colour coding, you'd need to modify the biplot code a bit or roll your own.
