Find lipid class of metabolites base on referenced Kendrick mass defect

Description

Find lipid class of metabolites base on referenced Kendrick mass defect

Usage

findlipid(list, mode = "pos")

Arguments

list	list with data as peaks list, mz, rt and group information, retention time should be in seconds
mode	'pos' for positive mode, 'neg' for negative mode and 'none' for neutral mass, only support [M+H] and [M-H] for each mode

Value

list list with dataframe with the lipid referenced Kendrick mass defect(RKMD) and logical for class
