Hi,
I am trying to identify duplicate values in a column in a date frame. The
duplicated function identifies the duplicate rows in the data frame but it
only does this for the second record, not both records. Is there a way to
mark both rows in the data frame as TRUE?
try this:
dfA$dups-duplicated(dfA$Value) | duplicated(dfA$Value, fromLast = TRUE)

Hello,
Please use dput(dfA) to post your data examples. The following is it's
output. All one has to do is to copy and paste to an R session to get
the data example.
dfA -
structure(list(Site = c(929L, 929L, 930L, 930L, 931L, 932L),
State = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = VA,
Thanks!!
That did the trick!!
