plotChr: Plotting sample chromatogram

In xdomingoal/erah-devel: Automated Spectral Deconvolution, Alignment, and Metabolite Identification in GC/MS-Based Untargeted Metabolomics

Plotting sample chromatogram

Description

Plot the sample chromatogram

Usage

plotChr(
  Experiment,
  N.sample = 1,
  type = c("BIC", "TIC", "EIC"),
  xlim = NULL,
  mz = NULL
)

## S4 method for signature 'MetaboSet'
plotChr(
  Experiment,
  N.sample = 1,
  type = c("BIC", "TIC", "EIC"),
  xlim = NULL,
  mz = NULL
)

Arguments

Experiment	A 'MetaboSet' S4 object containing the experiment.
N.sample	Integer. The number of the sample to query.
type	The type of plotting, Base Ion Chromatogram (BIC), Total Ion Chromatogram (TIC), or Extracted Ion Chromatogram (EIC).
xlim	The range in minutes, separated by comas: c(rt.min, rt.max) of the limits of plotting. By default, all the chromatogram is plotted.
mz	Just when EIC is selected. The range separated by comas: c(mz.min, mz.max) or a vector of numbers: c(50,67,80), of the masses to be ploted.

Examples

## Not run: 
plotChr(Experiment, 1, "BIC")

# Plots from minute 5 to 7.
plotChr(Experiment, 1, "TIC", xlim=c(5,7))  

# Plots from minute 5 to 7, and only the masses from 50 to 70.
plotChr(Experiment, 1, "EIC", mz=50:70 xlim=c(5,7))  

# Plots the EIC from minute 7 to 7.5, and only the masses 50, 54 and 70.
plotChr(Experiment, 1, "EIC", xlim=c(7,7.5), mz=c(50,54,70))
