Hi everyone,
I have a tibble with various ids and associated information.
I need to add a new column to this tibble that retrieves a specific 'y'
value from a different tibble that has some of the mentioned ids in the
first column and a 'y' value in the second one. If the id, and so the 'y'
value is found, it will be included; otherwise, 'NA' will be used.
Could you please help me?
Thanks,
Alessandro
