Thanks very much to both of you. Duplicated does exactly what I'm looking
for.
Sorry -- I didn't realize that I was supposed to provide a subset of my data
frame. A little late now, but here it is -- the data frame is called
SubInfo, and it gives background informations on subjects from a survey
As Jim suggested, the duplicated() function should help.
If I understand what you're after, you could try something like this. I
assumed that the name of your data frame was "df".
selrows <- df$WorkerID %in% df$WorkerID[duplicated(df$WorkerID)]
# SubjectNumbers with duplicate WorkerIDs
df$Subj
?duplicated
Hard to give a specific solution unless you follow the posting guide
and provide a subset of the data to test on.
