agree: Simple and extended percentage agreement
In irr: Various Coefficients of Interrater Reliability and Agreement

Description Usage Arguments Details Value Author(s) See Also Examples

Computes simple and extended percentage agreement among raters.

1	agree(ratings, tolerance=0)

`ratings`	n*m matrix or dataframe, n subjects m raters.
`tolerance`	number of successive rating categories that should be regarded as rater agreement (see details).

Missing data are omitted in a listwise way.
Using extended percentage agreement (tolerance!=0) is only possible for numerical values. If tolerance equals 1, for example, raters differing by one scale degree are interpreted as agreeing.

A list with class '"irrlist"' containing the following components:

`$method`	a character string describing the method applied for the computation of interrater reliability.
`$subjects`	the number of subjects examined.
`$raters`	the number of raters.
`$irr.name`	a character string specifying the name of the coefficient.
`$value`	coefficient of interrater reliability.
