[R] Manually inserting an extra tick on the y axis in ggplot2
?Oh yes, looks good. I misread your request and thought that you wanted it integrated with the labels on the y-axis.

I wanted a horizontal line with a y intercept of 12.6. I set m <- 12.6 I drew the line with geom_hline then added?geom_text(aes(0,m,label =?m, vjust = -1)) which worked just fine. ?

How can I insert the corresponding tick and its value on the y axis itself?
