I tried your proposition Sarah (I was answering to Berend when you posted
your answer).
Well it seems to work!
I just had to add afterwords a line to have my NAs again.
I converted values = 0 by NA (numeric() in the function did the contrary for
the calculation):
mydata[mydata==0] <- NA
At firs
You're moving the goal posts. If you need to deal with internal as
well as terminal NA values in a particular way, it would help to have
told us that up front.
Please give us some sample data that illustrates what you're really
trying to work with, and a full explanation of what you need to
accomp
Thanks for your answer too Berend.
Yes you're right about x[i+1]. You answered juste before me.
Well your idea of declaring all in numeric is great. It avoids my problem.
But actually I also have small missing data gaps in the rest of my data (in
the middle of numeric values).
And one of the aim of

Sorry, I should really have more coffee b
Thank you for your reply sarah.
Well actually I don't try to access x[i+1]. The line where you saw it starts
with #. It was just try I wanted to keep (sorry I should have removed it
before posting).
But I ask him to access to the next value if conditions in the loop are not
verified (restart the c

The reference to x[i+1] in a commented line so I don't think
Well, if i goes from 2 to length(x) and you try to access x[i+1], of
course odd things will happen. Why not construct the loop to
(length(x)-1) instead, so that x[i+1] is defined.

Hi dear R-users,
I have a question about a function I'm trying to improve.
How can I stop the function calculation at the last numeric value of my
data?
The problem is that the end of my data contains missing values (NAs). And
the aim of my function is to compare the first numeric value with the n
