How to increase point size or color palette of a PCA plot using the scater package for scRNA analysis

Question

[AB]

Hi,

I am using scater to analyze my single cell data. However the plotPCA function has a fixed point size and color palette. I couldn't find anything in the documentation that would help me increase point sizes or change the colors. I can always hack the SCEset and use ggplot. But is there anyway to do this using scater?

Thanks

Hello, I just saw your post. How did you do it exactly? I tried geom_point but I couldn't do it.

Thank you.

Hi You can adjust the size of the points by adding geom_point() to plotPCA function (e.g geom_point(size = 4)
