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 (t

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)

[R] Remove duplicate elements in lists via recursive indexing

Dear list, I'm trying to solve something pretty basic here, but I can't really come up with a good solution. Basically, I would just like to remove duplicated named elements in lists via a their respective recursive indexes (given that I have a routine that identifies these recursive indexes)
