FindCommon {MScombine} | R Documentation |
Find entities presented in both polarities
Description
Takes matrices from positive and negative ionization mode and find entities in common.
Usage
FindCommon(POSITIVE, NEGATIVE, ADDUCTS, Masstolerance, RTtolerance)
Arguments
POSITIVE |
A matrix with positive entities information (Compound Name, Mass, RT, and multiple columns with the area of the compound in samples). |
NEGATIVE |
A matrix with positive entities information (Compound Name, Mass, RT, and multiple columns with the area of the compound in samples). |
ADDUCTS |
A matrix with positive adducts, negative adducts and their difference in mass. |
Masstolerance |
The tolerance in Da when considering the adducts that can be present in both matrices. |
RTtolerance |
The tolerance of retention time when comparing both polarities. It should be in the same units as the RT in POSITIVE and NEGATIVE matrices. |
Examples
