chemical.dissimilarity: Chemical dissimilarity.

In MetChem: Chemical Structural Similarity Analysis

Chemical dissimilarity.

Description

This function calculates the structural dissimilarity between different metabolites using the simplified molecular-input line-entry system (SMILE) of each metabolite as input.

Usage

chemical.dissimilarity (smiles,method="tanimoto",type="extended")

Arguments

smiles	A vector of smile notations.
method	The method used to calculated the distance between molecular fingerprint ("tanimoto" as default). For more information see fp.sim.matrix function.
type	The type of fingerprint applied to the SMILEs ("extended" as default). For more information see get.fingerprint function.

Value

A list contains distance between fingerprints .
