Remove duplicates from a column R

Question

And I want the result to be:

Can anybody help me with an R script :-)?

Kind of ironic... removing duplicates is a duplicate :) – RHertel Jul 11 '15 at 11:32 — RHertel, Jul 11 '15 at 11:32

You can use duplicated or unique. Here, I am assuming that the column name is 'ID'

 df1[!duplicated(df1$ID),,drop=FALSE]

Or

  library(data.table)#v1.9.4+
  unique(setDT(df1), by='ID')
