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
