R help - Nov 2023 - Adding columns to a tibble based on a value in a different tibble

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

I think a simple reproducible example ("reprex") may be necessary for
you
to get a useful reply. Questions with vague specifications such as yours
often result in going round and round with attempts to clarify what you
mean without a satisfactory answer. Clarification at the outset with a
reprex may save you and others a lot of frustration.

Cheers,
Bert
