Produces a data frame which can be used by the compareR function using values commonly found in published literature. Useful for reviews and meta-analyses.
dataframeR(s11, s10, s01, s00, r11, r10, r01, r00)A data frame populated with zeros and ones indicating positive or negative test results which can be passed to the compareR function.
Number of cases where Test 1 is positive, Test 2 is positive and gold standard is positive.
Number of cases where Test 1 is positive, Test 2 is negative and gold standard is positive.
Number of cases where Test 1 is negative, Test 2 is positive and gold standard is positive.
Number of cases where Test 1 is negative, Test 2 is negative and gold standard is positive.
Number of cases where Test 1 is positive, Test 2 is positive and gold standard is negative.
Number of cases where Test 1 is positive, Test 2 is negative and gold standard is negative.
Number of cases where Test 1 is negative, Test 2 is positive and gold standard is negative.
Number of cases where Test 1 is negative, Test 2 is negative and gold standard is negative.
Understanding the parameter names: s & r represent positive and negative results for the gold standard test, respectively. The first digit represents a positive (1) or negative (0) result for Test 1. The second digit represents a positive (1) or negative (0) result for Test 2.
