[R] Problem in graph plotting

[FMH]

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)))
