Dear R family,
I have a question about how to detect some duplicate numeric observations.
Suppose that I have two variables dataset.
order value
1 0.52
2 0.23
3 0.43
4 0.21
5 0.32
6 0.32
7 0.32

9 0.32
10 0.12
11 0.46
12 0.09
13 0.32
14 0.25
;
Could you help me indicate where the
Try this:
DF[duplicated(DF$value),]

# go both ways to capture all duplicates
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
