Computes Cohen's kappa coefficient and standard error for two raters when data is a contingency table.

1 2	kappa2.table(ratings, weights = diag(ncol(ratings)), conflev = 0.95, N = Inf, print = TRUE)

`ratings`	a `q x q` contingency table showing the distribution of subjects by rater where `q` is the number of categories
`weights`	a vector of weights the same length as the number of categories
`conflev`	confidence level
`N`	used as denominator in finite population correction
`print`	logical; if `TRUE`, prints a summary of the agreement
