I wonder if it is possible to plot pca biplot results with ggplot2. Suppose if I want to display the following biplot results with ggplot2
fit <- princomp
Here is the simplest way through ggbiplot:
ggbiplot
library(ggbiplot) fit <- princomp(USArrests, cor=TRUE) biplot(fit)
ggbiplot(fit, labels = rownames(USArrests))
