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

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

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

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

(length(x)-1) instead, so that x[i+1] is defined.
