A contingency Table is a 2x2 matrix that contains the counts of all combinations of positive and negative ratings made by two raters.



The contingency Table is an object of class matrix with two rows and two columns. The ordering of the combination vector input to the matrix is as follows: c(Rater1Positive & Rater2Positive, Rater1Negative & Rater2Positive, Rater1Positive & Rater2Negative, Rater1Negative & Rater2Negative).


#An example contingencyTable ct = matrix(c(3,2,1,34), nrow = 2, ncol = 2) #This contingencyTable is included in the package under the variable name "contingencyTable".
