plotAnalyteXICs {DIAlignR} | R Documentation

## Plot extracted-ion chromatogram.

### Description

Plot extracted-ion chromatogram.

### Usage

    plotAnalyteXICs(
      analyte,
      run,
      dataPath = ".",
      maxFdrQuery = 1,
      XICfilter = "sgolay",
      polyOrd = 4,
      kernelLen = 9,
      runType = "DIA_proteomics",
      oswMerged = TRUE,
      peakAnnot = NULL,
      Title = NULL
    )

### Arguments

`analyte` | (integer) an analyte is a PRECURSOR.ID from the osw file.
`run` | (string) Name of a mzml file without extension.
`dataPath` | (string) path to mzml and osw directory.
`maxFdrQuery` | (numeric) A numeric value between 0 and 1. It is used to filter features from osw file which have SCORE_MS2.QVALUE less than itself.
`XICfilter` | (string) must be either sgolay, boxcar, gaussian, loess or none.
`polyOrd` | (integer) order of the polynomial to be fit in the kernel.
`kernelLen` | (integer) number of data-points to consider in the kernel.
`runType` | (char) This must be one of the strings "DIA_proteomics", "DIA_Metabolomics".
`oswMerged` | (logical) TRUE for experiment-wide FDR and FALSE for run-specific FDR by pyprophet.
`peakAnnot` | (numeric) Peak-apex time.
`Title` | (logical) TRUE: name of the list will be displayed as title.

### Value

A plot to the current device.
