[R] Add ablines

[a.antonini010 at hotmail.com]

Good morning,
I have some problem adding ablines in Rstudio.
The lines drew by the software doesen’t match with the added values, what can I do?

pfaOK<-qcc(D[!trial], sizes=size[!trial], type="p", nsigmas=2, data.name="Polli positivi al Campylobacter")
pfaOK1<-qcc(D[!trial], sizes=size[!trial], type="p", data.name="Polli positivi al Campylobacter")

abline(h=pfaOK$limits[1], lty=1, col="red")
abline(h=pfaOK$limits[2], lty=1, col="red")

abline(h=0.02204175, col="red")
abline(h=0.1996249, col="red")

abline(h=2.204175, col="red")
abline(h=19.96249, col="red")

Thanks for the attention,
                               Arianna
