[R] biplot

Wed Jun 22 17:56:02 CEST 2016

I should have mentioned that the points are invisible without the labels and there is no way to use plot symbols. Something like this is probably what you wanted.

> biplot(prcomp(x), xlabs=rep("*", 50), ylabs=rep("", 10))

Gives you the arrows and asterisks for the points. But labeling them is not easy since the coordinates are based on the columns:

> par("usr")
[1] -6.705729  7.179791 -6.705729  7.179791

The xlabs= (rows) and ylabs= (columns) arguments handle the labels, but they do not recycle so you need to specify values for each row and each column:

> set.seed(42)
> x <- matrix(rnorm(500), 50, 10)
> biplot(prcomp(x), xlabs=rep("", 50), ylabs=rep("", 10))

Hey,

Does anyone know how to remove labels from a biplot? I want to input them
manually as they are currently overlapping.

Thanks
