finterS-methods {msbase}R Documentation

Intersection of two vectors, Massvectors

Description

Returns the intersecting (entries) of the first argument

Arguments

obx see below in Methods section
oby see below in Methods section
error measurement error in e.g. Da or as relative error in parts per million (ppm)
ppm if TRUE then error in parts per million(ppm), in arbitrary units otherwise.
uniq if TRUE compute non-crossing matching.

Value

Massvector

Methods
