filterPpmError {Autotuner} | R Documentation

## filterPpmError

### Description

This function computes an estimate for the ppm error threshold.

### Usage

    filterPpmError(
      approvedPeaks,
      useGap,
      varExpThresh,
      returnPpmPlots,
      plotDir,
      observedPeak,
      filename
    )

### Arguments

`approvedPeaks` | This is a data.frame with information on bins retained after filtering with user input mz error threshold and continuity checks.
`useGap` | Parameter carried into checkEICPeaks that tells Autotuner whether to use the gap statustic to determine the proper number of clusters to use during ppm parameter estimation.
`varExpThresh` | Numeric value representing the variance explained threshold to use if useGap is false.
`returnPpmPlots` | Boolean value that tells R to return plots for ppm distributions.
`plotDir` | Path where to store plots.
`observedPeak` | A list with names 'start' and 'end' containing scalar values representing the calculated peak boundary points
`filename` | A string containing the name of the current data file being analyzed.

### Details

A distribution is created from the set of all ppm values identified. The most dense peak of this distribution is assumed to represent the standard ppm error of the data.

### Value

This function returns a scalar value representing ppm error estimate.
