plotEIC-methods {xcms} | R Documentation

## Plot extracted ion chromatograms for specified m/z range

### Description

Plot extracted ion chromatogram for m/z values of interest. The raw data is used in contrast to `plotChrom` which uses data from the profile matrix.

### Arguments

`object` | `xcmsRaw` object
`mzrange` | m/z range for EIC. Uses the full m/z range by default.
`rtrange` | retention time range for EIC. Uses the full retention time range by default.
`scanrange` | scan range for EIC
`mzdec` | Number of decimal places of title m/z values in the eic plot.
`type` | Speficies how the data should be plotted (by default as a line).
`add` | If the EIC should be added to an existing plot.
`...` | Additional parameters passed to the plotting function (e.g. `col` etc).

### Value

A two-column matrix with the plotted points.

### Methods

object = "xcmsRaw"

  `plotEIC(object, mzrange = numeric(), rtrange = numeric(), scanrange = numeric(), mzdec=2, type="l", add=FALSE, ...)`
