plot_RLum.Data.Curve: Plot function for an RLum.Data.Curve S4 class object

In R-Lum/Luminescence: Comprehensive Luminescence Dating Data Analysis

Plot function for an RLum.Data.Curve S4 class object

Description

The function provides a standardised plot output for curve data of an RLum.Data.Curve S4-class object.

Usage

plot_RLum.Data.Curve(
  object,
  par.local = TRUE,
  norm = FALSE,
  smooth = FALSE,
  ...
)

Arguments

object	RLum.Data.Curve (required): S4 object of class RLum.Data.Curve
par.local	logical (with default): use local graphical parameters for plotting, e.g. the plot is shown in one column and one row. If par.local = FALSE, global parameters are inherited.
norm	logical character (with default): whether curve normalisation should occur (FALSE by default). Alternatively, the function offers modes "max" (used with TRUE), "last" and "huot", see details.
smooth	logical (with default): provides automatic curve smoothing based on the internal function .smoothing
...	further arguments and graphical parameters that will be passed to the plot function

Details

Only single curve data can be plotted with this function. Arguments according to plot.

Curve normalisation

The argument norm normalises all count values. To date the following options are supported:

norm = TRUE or norm = "max": Curve values are normalised to the highest count value in the curve

norm = "last": Curve values are normalised to the last count value (this can be useful in particular for radiofluorescence curves)

norm = "huot": Curve values are normalised as suggested by Sébastien Huot via GitHub:

y = (observed - median(background)) / (max(observed) - median(background))

The background of the curve is defined as the last 20% of the count values of a curve.

Value

Returns a plot.

Function version

0.2.6

Note

Not all arguments of plot will be passed!
