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, the function uses its 'exprs' slot
... arguments passed to spearman.dist:
abs
if TRUE, then 1-|SPEAR| else 1-SPEAR, 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

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.
