I am a beginner R learner, so bear with me if I say something incoherent.
I have a large vector variable holding exactly 5000 elements, and would like to know what these are, knowing that there are several repetitions. An introduction to R doesn't seem to say anything besides basic data structures, and I don't know if R offers this feature as built-in.
If there is no such "data structure", is there some built-in function to filter out repeated elements in a vector or list?
I'd also recommend looking into the sets library. Install it with install.packages('sets') and see, if the following works for you.
sets::as.set(c(1, 1, 2, 4, 3, 5, 5, 5))
# output: {1, 2, 3, 4, 5}
R doesn't have a built-in set data structure, you need to download a library called sets. for more information about sets library visit : https://www.rdocumentation.org/packages/sets/versions/1.0-21/topics/set
