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

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.

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)

## 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',
