bertinrangescore: Range standardisation of a matrix

In bertin: Bertin matrix display

Description

Calculate range standardised matrix for Bertin analysis.

Usage

bertinrangescore(z, var.orientation = c("byrow", "bycolumn", "global"), na.rm = TRUE, finite = FALSE)

Arguments

z	A data matrix
var.orientation	"byrow", "bycolumn", "global"). By defaults, following Bertin's conventions variables are in rows. Use var.orientation="bycolumn" for R conventions.
na.rm	passed to range
finite	passed to range

Details

Calculates (x-min(x))/ ( max(x)-min(x). If range(x) has zero length, one is returned as value.

Value

scores

An augmented matrix of rank scores. The matrix has the class "bertin" and carries the attributes: var.orientation cached. This list is subject to change.
