Re: [R] How to get the duplicated elements from a vector?

[Dimitris Rizopoulos]

check duplicated(), e.g.,

x <- c("yes", "no", "yes", "yes", "no", "not sure")
x[duplicated(x)]


I hope it helps.

Best,
Dimitris

Dear all,

    How can I get the duplicated elements from a vector? For example,

x <- c("yes", "no", "yes", "yes", "no", "not sure"), how can I filter out all the elements which occured >=2 times?

    Thanks for any help!

Regards,
Leon
