Interrater Reliability

Description

Function for Interrater Reliability.

Usage

agreement(
  data,
  vars,
  sft = FALSE,
  wght = "unweighted",
  exct = FALSE,
  kripp = FALSE,
  krippMethod = "nominal",
  bootstrap = FALSE
)

Arguments

data	The data as a data frame. The data should be in long format, where each row is a unique observation.
vars	A string naming the variable from data that contains the diagnosis given by the observer, variable can be categorical or ordinal.
sft	Boolean selection whether to show frequency table. Default is 'false'. If 'true', the function will show frequency table for each observer.
wght	A list for the argument weight (wght), for weighted kappa analysis. Default is 'unweighted'. 'squared' or 'equal' should be selected only with ordinal variables. The function gives error if the variable type is not ordinal. The default is 'unweighted'.
exct	Boolean selection whether to use exact kappa. Effects only more than 3 observers. Default is 'false'.
kripp	Boolean selection whether to calculate Krippendorff's alpha. Default is 'false'.
krippMethod	Specifies the measurement level for Krippendorff's alpha calculation.
bootstrap	Calculate bootstrap confidence intervals for Krippendorff's alpha.

Value

A results object containing:

results$irrtable					a table
results$text2					a html
results$text					a preformatted
results$krippTable					a table

Tables can be converted to data frames with asDF or as.data.frame. For example:

results$irrtable$asDF

as.data.frame(results$irrtable)
