Thank you for the code. I found that the coding does not work if there is an NA in dp variable. For instance;
#####################
dp <- c(1,4,NA,2,5,7,9,8,9,2)
tp <- 1:10
plot(tp,dp, type= 'l',ylim=rev(range(dp)))
#####################
If this is the case, how could we rewrite the coding?
Thank you
Fir

try this:
plot(tp,dp, type= 'l',ylim=rev(range(dp)))
