columnOverlapCoefficient: Pairwise jaccard/overlap coefficient can be calculated...

In ribiosUtils: Utilities from and Interface to the Bioinfo-C (BIOS) Library

Description

Pairwise jaccard/overlap coefficient can be calculated efficiently using matrix Pairwise overlap coefficient of binary matrix by column

Usage

columnOverlapCoefficient(x, y = NULL)

Arguments

x	An integer matrix, other objects will be coereced into a matrix
y	An integer matrix, other objects will be coereced into a matrix. In case of NULL, pairwise overlap coefficients by column of x is returned.

Value

A matrix of column-wise pairwise overlap coefficients of the binary matrix. NaN is reported when neither of the columns have any non-zero element.

Examples

set.seed(1887)
testMatrix1 <- matrix(rbinom(120, 1, 0.2), nrow=15)
columnOverlapCoefficient(testMatrix1)

testMatrix2 <- matrix(rbinom(150, 1, 0.2), nrow=15)
testMatrix12Poe <- columnOverlapCoefficient(testMatrix1, 
  testMatrix2)
