... The data.frame I used was: set.seed(1) dfbig <- data.frame(var1=sample(letters, 1000, replace = TRUE), var2=sample(LETTERS, 1000, replace = TRUE), freq=sample(1:10, 1000, replace = TRUE)) On the tiny data.frame, the base answer does well in my benchmarking, it just doesn't scale well to bigger ...
