# Create the profile of rankings

The plurality function is just a wrapper of tapproval with t=1

Borda count

\[ B(a) = 5 · 3 + 3 · 2 + 6 · 1 + 0 · 0 = 27 , B(b) = 3 · 3 + 6 · 2 + 5 · 1 + 0 · 0 = 26 , B(c) = 6 · 3 + 0 · 2 + 0 · 1 + 8 · 0 = 18 , B(d) = 0 · 3 + 5 · 2 + 3 · 1 + 6 · 0 = 13 . \]

To replicate this using the package. First, it is necessary to create the profile of rankings:

por <- parse_profile_of_rankings("6, c > b > a > d,
                                  5, a > d > b > c,
                                  3, b > a > d > c")
borda_count(por)
#> a ≻ b ≻ c ≻ d
