Add ablines

a.antonini010@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

A) Without your data, it is very difficult to see what your problem is. You need to include both data and code to create a reproducible example. [1][2][3]

I assume you are using the qcc package's qcc function.
example(qcc) gives an example of adding abline's to its plot:
  # add warning limits at 2 std. deviations
  q <- qcc(diameter[1:25,], type="xbar", newdata=diameter[26:40,],
plot=FALSE)
  (warn.limits <- limits.xbar(q$center, q$std.dev, q$sizes, 2))
  plot(q, restore.par = FALSE)
  abline(h = warn.limits, lty = 3, col = "chocolate")
and help(qcc) describes the 'restore.par' argument:
  restore.par: a logical value indicating whether the previous ‘par’
            settings must be restored. If you need to add points, lines,
            etc. to a control chart set this to ‘FALSE’.
