I want to plot biplots. I have seen the function biplot, but there are

1. My observations, and my variables, fall into groups. Is there a way to,
say, plot the observations in several different colours, according to

& 3rd PCs, and did this:
test <- edit(loadings(cv.prc.spr))
test.1 <- test[,1]
test.2 <- test[,2]
test.3 <- test[,3]
x0 <- 0
y0 <- 0
i <-
