Reduce label size in Volcano Plot

Question

[Ranan Jyoti Sarma]

I have constructed a volcano plot by modifying the code from:

https://www.gettinggeneticsdone.com/2016/01/repel-overlapping-text-labels-in-ggplot2.html.

I would like to reduce the size of the gene name in label. Is there anyone to help me out?

Just to note, there are dedicated packages for volcano: https://bioconductor.org/packages/release/bioc/html/EnhancedVolcano.html

Maybe try setting the size? geom_text_repel(size = 1) ?
