crash in plot_DetPlot() iwth analyse_function = "analyse_pIRIRSequence"

[mcol]

This crashes:

data(ExampleData.BINfileData, envir = environment())
object <- Risoe.BINfileData2RLum.Analysis(CWOSL.SAR.Data, pos = 1)

plot_DetPlot(
    object,
    method = "expansion",
    signal.integral.min = 1,
    signal.integral.max = 3,
    background.integral.min = 900,
    background.integral.max = 1000,
    analyse_function = "analyse_pIRIRSequence",
    analyse_function.control = list(
      fit.method = "LIN"),
    verbose = FALSE,
    n.channels = 2)

# Error in `levels<-`(`*tmp*`, value = as.character(levels)) : 
#   factor level [4] is duplicated

The error happens in this code inside analyse_SAR.CWOSL():

Luminescence/R/analyse_SAR.CWOSL.R

Lines 700 to 702 in 759a114

	temp.LnLxTnTx <- data.frame(
	Name = factor(x = temp.DoseName[,"Name"], levels = temp.DoseName[,"Name"]),
	Repeated = as.logical(temp.DoseName[,"Repeated"]))

That error can be fixed using levels = unique(temp.DoseName[, "Name"]), but then the crash moves a bit forward:

Error : [plot_pIRIRSequence()] An error occurred, analysis skipped. Check your sequence!
In addition: Warning message:

In addition: Warning message:

  [merge_RLum()] Nothing was merged as the object list was found to be empty or contains only one object!

When the merge fails because there are no valid results, we should stop rather than continuing.

Fixed by #211.
