Dear R family,
I have a question about how to detect some duplicate numeric observations.
Suppose that I have two variables dataset.

Hello Moohwan,
Look at ?duplicated for example:
> x
[1] 1 1 2 2 3 3
> duplicated(x)
[1] FALSE TRUE FALSE TRUE FALSE TRUE
If your end goal is to get rid of the duplicates, take a look at ?unique
> unique(x)
[1] 1 2 3
Best Regards,
Josh

Try this:
