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, abs = TRUE, diag = FALSE, upper = FALSE)

Arguments

x n by p matrix
abs if TRUE, then 1-|SPEAR| else 1-SPEAR
diag if TRUE, diagonal of the distance matrix will be displayed
upper if TRUE, upper triangle of the distance matrix will be displayed

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.
