Find Major Features

Load a mass spec file and find high intensity mzs

tidy_mzR_plot_major_features(
  tidy_mzR,
  clamr_config,
  ic_cutoff_fraction = 1/20,
  signal_cv_cutoff = 0.2
)

Arguments

tidy_mzR

output of tidy_mzR_from_msfile

clamr_config

a named list of mass spec parameters with special formatting of instrument tolerances generated by build_clamr_config.

ic_cutoff_fraction

mzs to extract as a fraction of the maximum ic

signal_cv_cutoff

mzs with a coefficient of variation of less than this value will be excluded since they are not eluting

Value

a ggplot2 grob
