computeKappa(pri_col, rel_col, *codes)

Computes Cohen’s kappa for a primary and reliability column. Cells between the two columns are matched by their onset time. Computes a contingency table and kappa score for each specified code.

Parameter Type Description
pri_col String or RColumn object Name (or column object) of primary coder’s column.
rel_col String or RColumn object Name (or column object) of reliability coder’s column.
*codes List Names of codes to compute scores for.
