tau.dist {bioDist}R Documentation

Kendall's tau correlational distance

Description

Calculate pairwise Kendall's tau correlational distances, i.e. 1-TAU or 1-|TAU|, for all rows of the input matrix and return an instance of the dist class.

Usage

tau.dist(x)

Arguments

x n by p matrix or ExpressionSet; if x is an ExpressionSet, the function uses its 'exprs' slot
... arguments passed to tau.dist:
abs
if TRUE, then 1-|TAU| else 1-TAU, default is TRUE
diag
if TRUE, diagonal of the distance matrix will be displayed, default is FALSE
upper
if TRUE, upper triangle of the distance matrix will be displayed, default is FALSE

Details

Row-wise correlations are computed by calling the cor function with the appropriate arguments.

Value

One minus the row-wise Kendall's tau correlations are returned as an instance of the dist class.
