QQ plots of p-values in R using ggplot2
Way back will wrote on this topic. See his previous post for Stata code for doing this. Unfortunately the R package that was used to create QQ-plots here has been removed from CRAN, so I wrote my own using ggplot2 and some code I received from Daniel Shriner at NHGRI.
Of course you can use R’s built-in qqplot() function, but I could never figure out a way to add the diagonal using base
