R Documentation

Acessor functions for the feature mapping table in a metaponeResult object.

Description

Returns a list containing the mapped features in each pathway.

Usage

## S4 method for signature 'metaponeResult'
ftable(object)

Arguments

object

A metaponeResult object.

Details

Each pathway is represented by a data.frame as an item in the list object. The dataframe include information of m.z, retention.time, p.value, statistic, HMDB_ID, theoretical m.z, ion.type, fractional counts.

Value

The method returns a list. Each item is for a pathway. Matched significant metabolites are included.
