In DTComPair: Comparison of Binary Diagnostic Tests in a Paired Study Design

Tabulate Single Binary Diagnostic Test vs. Gold-Standard

Description

Produces a contingency table of results from a single binary diagnostic test vs. the gold-standard results.

Usage

tab.1test(d, y, data = NULL, testname, ...)

Arguments

d	A numeric vector specifying the gold-standard results (1 = presence of disease, 0 = absence of disease).
y	A numeric vector specifying the results of the diagnostic test (1 = positive, 0 = negative).
data	An optional data frame, list or environment containing the required variables d and y.
testname	An optional character variable specifying the name of the diagnostic test, e.g. c("Test A"). If not supplied, the variable name is used as the testname.
...	Additional arguments (usually not required).

Value

Returns a list of class tab.1test:

tab.1test	A contingency table (matrix) of test results. Diseased Non-diseased Total Test pos. ... ... ... Test neg. ... ... ... Total ... ... ...
testname	The name of the diagnostic test.

Note

Objects of class tab.1test are required as arguments for acc.1test, a function to compute the accuracy of a binary diagnostic test.

Examples

data(Paired1) # Hypothetical study data 
a <- tab.1test(d=d, y=y1, data=Paired1)
str(a)
