Description

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.

Usage

dataframeR(s11, s10, s01, s00, r11, r10, r01, r00)

Arguments

s11	Number of cases where Test 1 is positive, Test 2 is positive and gold standard is positive.
s10	Number of cases where Test 1 is positive, Test 2 is negative and gold standard is positive.
s01	Number of cases where Test 1 is negative, Test 2 is positive and gold standard is positive.
s00	Number of cases where Test 1 is negative, Test 2 is negative and gold standard is positive.
r11	Number of cases where Test 1 is positive, Test 2 is positive and gold standard is negative.
r10	Number of cases where Test 1 is positive, Test 2 is negative and gold standard is negative.
r01	Number of cases where Test 1 is negative, Test 2 is positive and gold standard is negative.
r00	Number of cases where Test 1 is negative, Test 2 is negative and gold standard is negative.
