plot_DRCSummary: Create a Dose-Response Curve Summary Plot

In Luminescence: Comprehensive Luminescence Dating Data Analysis

Create a Dose-Response Curve Summary Plot

Description

While analysing OSL SAR or pIRIR-data the view on the data is limited usually to one dose-response curve (DRC) at the time for one aliquot. This function overcomes this limitation by plotting all DRC from an RLum.Results object created by the function analyse_SAR.CWOSL in one single plot.

Usage

plot_DRCSummary(
  object,
  source_dose_rate = NULL,
  sel_curves = NULL,
  show_dose_points = FALSE,
  show_natural = FALSE,
  n = 51L,
  ...
)

Arguments

object	RLum.Results object (required): input object created by the function analyse_SAR.CWOSL. The input object can be provided as list.
source_dose_rate	numeric (optional): allows to modify the axis and show values in Gy, instead seconds. Only a single numerical values is allowed.
sel_curves	numeric (optional): id of the curves to be plotting in its occurring order. A sequence can be provided for selecting, e.g., only every 2nd curve from the input object
show_dose_points	logical (with default): enable or disable plot of dose points in the graph
show_natural	logical (with default): enable or disable the plot of the natural Lx/Tx values
n	integer (with default): the number of x-values used to evaluate one curve object. Large numbers slow down the plotting process and are usually not needed
...	Further arguments and graphical parameters to be passed. In particular: main, xlab, ylab, xlim, ylim, lty, lwd, pch, col.pch, col.lty, mtext

Details

If you want plot your DRC on an energy scale (dose in Gy), you can either use the option source_dose_rate provided below or your can SAR analysis with the dose points in Gy (better axis scaling).

Value

An RLum.Results object is returned:

Slot: @data

OBJECT	TYPE	COMMENT
results	data.frame	with dose and LxTx values
data	RLum.Results	original input data

Slot: @info

OBJECT	TYPE	COMMENT
call	call	the original function call
args	list	arguments of the original function call

Note: If the input object is a list a list of RLum.Results objects is returned.
