Adding ind labels to a pca biplot

Question

I'm making a biplot for a PCA, but the individuals are only showing up as points. Is there any way to keep the variables and individuals grouped and have the name label appear over each point? I ask this because it's important to see the groups they belong to, but also to know which individual it is. I'm working with the fviz_pca_biplot() function.

I have tried to change the geometry, but when I do, the groups get lost. That's the pca biplot without the labels over every individual.

Answer 1

I think you can do it by adding row names on the original data, which is used to calculate the the PCAs. Also you should add geom on the fviz_biplot() to geom = c("point","text”). As you don’t give the codes, I can’t give you the exact solution.
