set_binomialfreq: Binomial frequency rankings from pairwise contests

Description

Binary comparisons from a ranking object. Ties are not taken into account, then they are added as NA's.

Usage

set_binomialfreq(object, drop.null = FALSE, disaggregate = FALSE)

Value

A data.frame with binary rank of pairwise contests:

player1

a factor with n levels for the first player in the contests

player2

a factor with n levels (same as player1) for the second player in the contests

win1

number of times player1 wins against player2

win2

number of times player2 wins against player1

Arguments

object

an object of class rankings, grouped_rankings or paircomp

drop.null

logical, an optional argument to remove null contests

disaggregate

logical, if TRUE binaries are disaggregated by individual contests
