Hi ElMaestro,

❝ Man, I never looked at the rank function until now. But it seems to be the important distinction between rank and order that answers my question.

Yep. Don’t know what you want to achieve, but:

L <- c(0.000000, 5161.096198, 18218.849691, 24977.065020, 108495.506990, 114018.413824, 459809.038038, 8691576.342850, 9917785.333365, 6694756.609860) df <- data.frame(L = L, rk = rank(L)) names(df)[2] <- "rank(L)" # cosmetics print(df) L rank(L) 1 0.000 1 2 5161.096 2 3 18218.850 3 4 24977.065 4 5 108495.507 5 6 114018.414 6 7 459809.038 7 8 8691576.343 9 9 9917785.333 10 10 6694756.610 8 print(df[with(df, order(L)), ]) L rank(L) 1 0.000 1 2 5161.096 2 3 18218.850 3 4 24977.065 4 5 108495.507 5 6 114018.414 6 7 459809.038 7 10 6694756.610 8 8 8691576.343 9 9 9917785.333 10 print(df[with(df, order(rank(L))), ]) # same L rank(L) 1 0.000 1 2 5161.096 2 3 18218.850 3 4 24977.065 4 5 108495.507 5 6 114018.414 6 7 459809.038 7 10 6694756.610 8 8 8691576.343 9 9 9917785.333 10

If you simply want to order the L vector, use:

L <- L[order(L)]
