Project all points in PCA plot to the x-axis

[Dan3]

Hi,

I have done PCA on my data. It has a lot of features, so I want to project all points in the PCA plot to PC1 to see the separation between all points.

I am not entirely sure on how to do it. I have been trying to use the ggplot function, but it seems like it requires at least x and y axis to be able to work.

Any recommendations on how to perform this will be much appreciated.

Thank you.

Maybe you could provide a reproducible example of your output?

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
