I'm working with biplot function to figure out some assumptions about certain individuals, the problem is that I have plenty of individuals and I can't find those I want to study. I've searched a lot and I have come to the conclusion that there is no way to, for example, change the colour of some individuals in a biplot. I have no idea, I have tried everything and nothing works. The only thing I want is to highlight in the biplot some individuals, I don't mind how.
I tried everything, with biplot, fivz_, adding geom_point, but didn't work.
I'm working with the USArrests data, and the individuals are South Carolina, Mississippi and North Carolina.
