xcmsFragments-class {xcms} | R Documentation |
This class is similar to xcmsSet
because it stores peaks
from a number of individual files. However, xcmsFragments keeps
Tandem MS and e.g. Ion Trap or Orbitrap MS$^n$ peaks, including the
parent ion relationships.
Objects can be created with the xcmsFragments
constructor and filled with peaks using the collect method.
peaks
:signature(object = "xcmsFragments")

signature(object = "xcmsFragments")
: prints a (text based) pseudo-tree of the peaktable to display the dependencies of the peaks among each other.
signature(object = "xcmsFragments")
: print a human-readable
description of this object to the console.
