[R] how do I add text lables on QQ plot

[Ana Marija]

Hello,

I am making QQ plot via:

library(ggman)
qq(fdr2_sorted$FDR.q.val2, main = "RG_All", pch = 17,
col=fdr1_sorted$group, cex = 1, las = 1)

data frames used look like this:

> head(fdr1_sorted)

and I would like to get the plot like the one in attach.

Please advise,
