Hi Timothy,
and thanks for the answer. Loops where exactly what I was trying to
avoid as much as possible. My initial idea was that that once I had
recursive indexes at my disposal (which were retrieved over recursive
loops), I could simply use it in a similar manner as we do with indexes

Dear Janko,
I think requires a for loop. The approach I took here was mark the dups, then
dump them all in one hit:
testData = expand.grid(letters[1:4],c(1:3))
testData$keep=F
uniqueIDS = unique(testData$Var1)
for(thisID in uniqueIDS) {
firstCaseOnly = match(thisID,testData$Var1)
2 matches
