spearman.dist: Spearman correlational distance

In Bioconductor/bioDist: Different distance measures

Spearman correlational distance

Description

Calculate pairwise Spearman correlational distances, i.e. 1-SPEAR or 1-|SPEAR|, for all rows of a matrix and return a dist object.

Usage

spearman.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 spearman.dist: absif TRUE, then 1-|SPEAR| else 1-SPEAR; 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

We call cor with the appropriate arguments to compute the row-wise correlations.

Value

One minus the Spearman correlation, between rows of x, are returned, as an instance of the dist class.
