如何在R中制作没有标签的双图

Question

I used

biplot(prcomp(data, scale.=T), xlabs=rep("·", nrow(data)))

but it did not work to omit the labels. Even if I remove the labels my plot is so messy and ugly which can be seen below! I also need to show the percentage of PCs on axes

I used the following command to plot the image

biplot(prcomp(data, scale.=T), xlabs=rep("·", nrow(data)), ylabs = rep("·", ncol(data)))

Try this one

\devtools::install_github("sinhrks/ggfortify")
library(ggfortify)
ggplot2::autoplot(stats::prcomp(USArrests, scale=TRUE), label = FALSE, loadings.label = TRUE)
