Description Usage Arguments Value Author(s) Examples

In the case two dependent tests shall be compared a fourfold table is mostly needed. count.fourfold counts the numbers of concordance and discordance of both tests.

1	count.fourfold(data, col.test1, col.test2)

`data`	name of the data
`col.test1`	number of column representing the first test
`col.test2`	number of column representing the second test

A vector containing the four entries of the fourfold table, row wise listed

# create a data set with zero and ones for each of both tests
v1=c(rep(1,10),rep(0,4),rep(1,8),rep(0,8))
v2=c(rep(0,10),rep(1,5),rep(0,5),rep(1,10))
n=c(seq(1,30,1))
new=cbind(n,v1,v2)
# count the number of concordance and discordance
count.fourfold(new,1,2)
