R package sklarsomega provides tools for measuring agreement using Sklar's omega coefficient, which subsumes Krippendorff's alpha coefficient, which in turn subsumes a number of other well-known agreement coefficients. The package permits users to apply the omega methodology to nominal, ordinal, interval, or ratio scores; can accommodate any number of units, any number of coders, and missingness; and can measure intra-coder agreement, inter-coder agreement, and agreement relative to a gold standard. Classical inference is available for all levels of measurement while Bayesian inference is available for interval data and ratio data only.
