rater_agreement: rater_agreement

Description

rater_agreement calculates the percent agreement between each rater and the other raters who coded the same subjects.

Usage

rater_agreement(object_name, rater_column, subject_column, coding_column)

Value

A tibble where each row notes the percent agreement between rater i and all other raters who coded the same subjects (percent_agree). The n_multi_coded column notes how many subjects have been coded by rater i that have also been coded by other raters (i.e., the denominator for the percent_agree value).

Arguments

object_name

A dataframe or tibble containing raters' codings. Each row should contain the assigned coding from a given rater-subject.

rater_column

The name of the column containing the raters' names as a string.

subject_column

The name of the column containing the names of the subjects being coded as a string.

coding_column

The name of the column containing the codings assigned by the raters as a string.
