tau.dist: Kendall's tau correlational distance

In Bioconductor/bioDist: Different distance measures

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, then the function uses its 'exprs' slot.
...	arguments passed to tau.dist: absif TRUE, then 1-|TAU| else 1-TAU; default is TRUE. diagif TRUE, then the diagonal of the distance matrix will be displayed; default is FALSE. upperif TRUE, then the upper triangle of the distance matrix will be displayed; default is FALSE. samplefor the ExpressionSet method: if TRUE (the default), then distances are computed between samples.

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. Note that this can be extremely slow for large data sets.
