\arguments{
\item{object}{\linkS4class{RLum.Analysis} or \link{list} of \linkS4class{RLum.Analysis} objects (\strong{required}):
input object containing data for analysis.
If a \link{list} is provided the functions tries to iterate over each element
in the list.}

\item{signal.integral.min}{\link{integer} (\strong{required}):
lower bound of the signal integral. Provide this value as vector for different
integration limits for the different IRSL curves.}

\item{signal.integral.max}{\link{integer} (\strong{required}):
upper bound of the signal integral. Provide this value as vector for different
integration limits for the different IRSL curves.}

\item{background.integral.min}{\link{integer} (\strong{required}):
lower bound of the background integral. Provide this value as vector for
different integration limits for the different IRSL curves.}

\item{background.integral.max}{\link{integer} (\strong{required}):
upper bound of the background integral. Provide this value as vector for
different integration limits for the different IRSL curves.}

\item{dose.points}{\link{numeric} (\emph{optional}):
a numeric vector containing the dose points values. Using this argument overwrites dose point
values in the signal curves.}

\item{sequence.structure}{\link{vector} \link{character} (\emph{with default}):
specifies the general sequence structure. Allowed values are \code{"TL"} and
any \code{"IR"} combination (e.g., \code{"IR50"},\code{"pIRIR225"}).
Additionally a parameter \code{"EXCLUDE"} is allowed to exclude curves from
the analysis (Note: If a preheat without PMT measurement is used, i.e.
preheat as none TL, remove the TL step.)}

\item{plot}{\link{logical} (\emph{with default}):
enable/disable the plot output.}

\item{plot_singlePanels}{\link{logical} (\emph{with default}):
enable/disable plotting of the results in a single windows for each plot.
Ignored if \code{plot = FALSE}.}

\item{...}{further arguments that will be passed to
\link{analyse_SAR.CWOSL} and \link{plot_DoseResponseCurve}. Furthermore, the
arguments \code{main} (headers), \code{log} (IRSL curves), \code{cex} (control
the size) and \code{mtext.outer} (additional text on the plot area) can be passed to influence the plotting. If the input
is a list, \code{main} can be passed as \link{vector} or \link{list}.}
}
\value{
Plots (\emph{optional}) and an \linkS4class{RLum.Results} object is
returned containing the following elements:

\tabular{lll}{
\strong{DATA.OBJECT} \tab \strong{TYPE} \tab \strong{DESCRIPTION} \cr
\code{..$data} : \tab  \code{data.frame} \tab Table with De values \cr
\code{..$LnLxTnTx.table} : \tab \code{data.frame} \tab with the \code{LnLxTnTx} values \cr
\code{..$rejection.criteria} : \tab \link{data.frame} \tab rejection criteria \cr
\code{..$Formula} : \tab \link{list} \tab Function used for fitting of the dose response curve \cr
\code{..$call} : \tab \link{call} \tab the original function call
}

The output should be accessed using the function \link{get_RLum}.

\description{
The function performs an analysis of post-IR IRSL sequences including curve
fitting on \linkS4class{RLum.Analysis} objects.
}
\details{
To allow post-IR IRSL protocol (Thomsen et al., 2008) measurement
analyses, this function has been written as extended wrapper for function
\link{analyse_SAR.CWOSL}, thus facilitating an entire sequence analysis in
one run. With this, its functionality is strictly limited by the
functionality provided by  \link{analyse_SAR.CWOSL}.

\strong{Defining the sequence structure}

The argument \code{sequence.structure} expects a shortened pattern of your
sequence structure and was mainly introduced to ease the use of the function.
For example: If your measurement data contains the following curves: \code{TL},
\code{IRSL}, \code{IRSL}, \code{TL}, \code{IRSL}, \code{IRSL}, the pattern in \code{sequence.structure}
becomes \code{c('TL', 'IRSL', 'IRSL')}. The second part of your sequence for one
cycle should be similar and can be discarded. If this is not the case (e.g.,
additional hotbleach) such curves must be removed before using the function.

\strong{If the input is a \code{list}}

If the input is a list of \linkS4class{RLum.Analysis} objects, every argument
can be provided as list to allow
for different sets of parameters for every single input element.
For further information see \link{analyse_SAR.CWOSL}.
}
\note{
Best graphical output can be achieved by using the function \code{pdf}
with the following options:

\code{pdf(file = "<YOUR FILENAME>", height = 18, width = 18)}

\examples{

### NOTE: For this example existing example data are used. These data are non pIRIR data.
###
##(1) Compile example data set based on existing example data (SAR quartz measurement)
##(a) Load example data
data(ExampleData.BINfileData, envir = environment())

##(b) Transform the values from the first position in a RLum.Analysis object
object <- Risoe.BINfileData2RLum.Analysis(CWOSL.SAR.Data, pos=1)

##(c) Grep curves and exclude the last two (one TL and one IRSL)
object <- get_RLum(object, record.id = c(-29,-30))

##(d) Define new sequence structure and set new RLum.Analysis object
sequence.structure  <- c(1,2,2,3,4,4)
sequence.structure <- as.vector(sapply(seq(0,length(object)-1,by = 4),
                                       function(x){sequence.structure + x}))

object <-  sapply(1:length(sequence.structure), function(x){
  object[[sequence.structure[x]]]
})

object <- set_RLum(class = "RLum.Analysis", records = object, protocol = "pIRIR")

##(2) Perform pIRIR analysis (for this example with quartz OSL data!)
## Note: output as single plots to avoid problems with this example
results <- analyse_pIRIRSequence(object,
     signal.integral.min = 1,
     signal.integral.max = 2,
     background.integral.min = 900,
     background.integral.max = 1000,
     fit.method = "EXP",
     sequence.structure = c("TL", "pseudoIRSL1", "pseudoIRSL2"),
     main = "Pseudo pIRIR data set based on quartz OSL",
     plot_singlePanels = TRUE)


##(3) Perform pIRIR analysis (for this example with quartz OSL data!)
## Alternative for PDF output, uncomment and complete for usage
\dontrun{
tempfile <- tempfile(fileext = ".pdf")
pdf(file = tempfile, height = 18, width = 18)
  results <- analyse_pIRIRSequence(object,
         signal.integral.min = 1,
         signal.integral.max = 2,
         background.integral.min = 900,
