peakPantheR_plotPeakwidth {peakPantheR} | R Documentation

## Plot peak value and peakwidth by acquisition time or in input order

### Description

For a single ROI, plot the peak value and peakwidth (RT, m/z, ...) of detected peaks across multiple samples, by acquisition time or in input order. If `rotateAxis=FALSE` x is run order / plot order, y is the `apexValue` / `widthMin` / `widthMax`, if `rotateAxis=TRUE` x is the measurement values and y the run order.

### Usage

    peakPantheR_plotPeakwidth(apexValue, widthMin = NULL, widthMax = NULL,
        acquTime = NULL, varName = "variable", sampleColour = NULL,
        rotateAxis = FALSE, verbose = TRUE)

### Arguments

`apexValue` | (float) vector of apex value
`widthMin` | (float) vector of detected peak minimum peakwidth value or NULL (if NULL no peakwidth)
`widthMax` | (float) vector of detected peak maximum peakwidth value or NULL (uf NULL no peakwidth)
`acquTime` | (POSIXct) vector of sample acquisition time as POSIXct or NULL (if NULL points are plotted in the order values are passed as input with the first on top or left)
`varName` | (str) Name of the variable to plot
`sampleColour` | (str) NULL or vector colour for each sample (same length as `apexValue`, `widthMin`, `widthMax`, `acquTime`)
`rotateAxis` | (bool) if TRUE x and y axis are reversed
`verbose` | (bool) if TRUE message when NA scans are removed

### Value

Grob (ggplot object)

### Examples

    ## Input data
    apexVal <- c(1, 2, 3, 4)
    minVal  <- c(0, 0, 2, 2)
    maxVal  <- c(2, 4, 4, 5)
    acqTime <- as.POSIXct(c('2017-07-13 21:06:14', '2017-07-14 21:06:14',
                            '2017-07-15 21:06:14', '2017-07-16 21:06:14'))
