I’m sorry, but that‘s not exactly what I was looking for. I obviously
didn’t explain properly:
Within my dataframe (df) I would like to find POT values that are not
linked. In my definition two maximum values are linked if walevel does not
fall below a certain value (the lower th
How about?
hi.rle<-rle(walevel>5.79)
lo.rle<-rle(walevel<5.36)
plot(walevel)
abline(h=5.8,col=2,lty=3)
abline(h=5.35,col=3,lty=3)
hi.lo.rle<-sort(c(cumsum(hi.rle$lengths),cumsum(lo.rle$lengths)))
abline(v=hi.lo.rle)
You can use the $values from the rle to sort things out. Probably

dear Tonja,
By plotting your data
plot(df)
it seems to me that you are looking for a piecewise linear
relationships. If this is the case, have a look to the package
segmented. You have to specify or not the number and the starting values
for the breakpoints

Dear List
I hope you can help me: I’ve got a dataframe (df) within which I am looking
for Peak Over Threshold values as well as the length of the events. An event
starts when walevel equals 5.8 and it should end when walevel equals the
lower threshold value (5.35).
