PlotEIC: Plot EIC

In xia-lab/MetaboAnalystR3.0: An R Package for Comprehensive Analysis of Metabolomics Data

Description

This functionn creates an extracted ion chromatogram (EIC) for a specific m/z and retention time. This is used for quality-control of raw m/s data.

Usage

PlotEIC(
  raw_data,
  rt_mn,
  rt_mx,
  mz_mn,
  mz_mx,
  aggreg = "sum",
  format = "png",
  dpi = 72,
  width = 9
)

Arguments

raw_data	The object created using the ImportRawMSData function, containing the raw MS data.
rt_mn	Numeric, specify the minimum bound of the retention time range.
rt_mx	Numeric, specify the maximum bound of the retention time range.
mz_mn	Numeric, specify the minimum bound of the m/z range.
mz_mx	Numeric, specify the maximum bound of the m/z range.
aggreg	Character, if "sum", creates a total ion chromatogram. If "max", creates a base peak chromatogram. By default it is set to "sum".
format	Character, input the format of the image to create.
dpi	Numeric, input the dpi of the image to create.
width	Numeric, input the width of the image to create.
