yes, you are perfectly right, sorry for that but for me was not so clear the
error message!

....and the third code example I posted (not working either) should be of
length one (if I'm not wrong again)
but most of all what is not included in my reproducible example and get a
bit confused my question is the case when the variable "date" contains dates
of many years and the objective is to count for each given year the julian
date starting from the first day of the corresponding year

how would you deal with this problem?

thanks a lot for your help
