Hello,
This is a very basic question, but I don'y know the answer. I have these data

delta <-
c(28.6-8.825,28.6-8.828,28.6-8.836,28.6-8.845,28.6-8.897,28.6-8.944,28.6-9.027,28.6-9.091,28.6-9.263,28.6-9.4,28.6-9.7,28.6-9.981, 28.6-10.287,28.6-10.48,28.6-10.684,28.6-10.875) ph <- c(4.4,4.6,4.8,5,5.2,5.4,5.6,5.8,6,6.2,6.4,6.6,6.8,7,7.2,7.4) plot(ph,delta,ylab=c(expression(Delta*delta)),xlab="pH")

Which kind of model can I fit on these, so that can I predict for a given delta the pH of my sample? Once the model is fitted, how can I plot it on the graph?
Best regards,

Dani
