Split Y-Axis of a manhattan plot in qqman (using R)

Question

[tacrolimus]

I am using qqman to plot a manhattan, my top hit is significantly above the others and is not showing up. I have edited the ylim to incorporate it but then that squashes the rest of the image down. Is there a way of putting in a y axis break in qqman or will I have to use another tool?

Many thanks

Example code:

manhattan(dt, ylim=c(0,20), cex.axis=0.6, col = c("darkorange", "deepskyblue3"), annotatePval=0.0001, genomewideline=-log10)0.05/p), suggestiveline = FALSE, chrlabs=c(1:22, "X"))
