Distance to the signature template

Description

This function returns a normalized distance to the signature template

Usage

	signatureDistance(
	              template,
	              data=NULL,
	              method = c("pearson","spearman","kendall","RSS","MAN","NB"),
	              fwts=NULL
	)

Arguments

`template`	A list with a template matrix of the signature described with quantiles = [0.025,0.100,0.159,0.250,0.500,0.750,0.841,0.900,0.975]
`data`	A data frame that will be used to compute the distance
`method`	The distance method.
`fwts`	A numeric vector defining the weight of each feature

Details

The distance to the template: "pearson","spearman" and "kendall" distances are computed using the correlation function i.e. 1-r. "RSS" distance is the normalized root sum square distance "MAN" Manhattan. The standardized L^1 distance "NB" Weighted Naive-Bayes distance
