Is it possible to change colour of the variables (vectors and their names) shown in ggbiplot? There is such option for observations, but I cannot find one for variables. Thanks.

Are you looking to change the color of each vector individually? Or just all of the vectors to a single color? – scribbles Jul 31 '15 at 17:33

Where is the code that loads the library and creates an example? – IRTFM Aug 01 '15 at 04:17
