addRetentionAtApex

dwide


  Calculates different summary retention time statistics
  for each peptide (a subsequence of a protein including
  post translational modifications).  The idea is that each
  peptide is supposed to have roughly the same retention
  time.


Provides methods for making inference in isobaric labelled
LC-MS/MS experiments, i.e. iTRAQ experiments. It provides a function that
reasonably parses a CSV-export from Proteome Discoverer(TM) into a data
frame that can be easily handled in R. Functions and methods are provided
for quality control, filtering, norming, and the calculation of response
variables for further analysis. The merging of multiple iTRAQ experiments
with respect to a reference is also covered.
