In gosset: Tools for Data Analysis in Experimental Agriculture

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)

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

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
