cohensKappa: Cohen's kappa coefficient

In MolecularPathologyLab/MmCMS: CMS-based Molecular Subtyping for CRC Mouse Tissue

Cohen's kappa coefficient

Description

Calculates Cohen's \kappa (kappa) coefficient for two equal length vectors.

Usage

cohensKappa(x, y, adjusted = TRUE)

Arguments

x	vector, coerced to factor.
y	vector, coerced to factor.
adjusted	logical. If adjusted=FALSE, the unadjusted accuracy is returned instead.

Details

Cohen's kappa coefficient measures the agreement between two categorical vectors. Zero indicates that the agreement is no better than expected by chance, while a value of one indicates perfect correspondence.

Value

If adjusted=TRUE, returns the kappa coefficient [-1,1]. If adjusted=FALSE, returns ordinary accuracy [0,1].

Note

Cases with NA in either input vector are ignored.
