RLum.Data.Spectrum-class: Class "RLum.Data.Spectrum"

Description

Class for representing luminescence spectra data (TL/OSL/RF).

Usage

# S4 method for RLum.Data.Spectrum
show(object)
# S4 method for RLum.Data.Spectrum
set_RLum(
  class,
  originator,
  .uid,
  .pid,
  recordType = "Spectrum",
  curveType = NA_character_,
  data = matrix(),
  info = list()
)
# S4 method for RLum.Data.Spectrum
get_RLum(object, info.object)
# S4 method for RLum.Data.Spectrum
names_RLum(object)
# S4 method for RLum.Data.Spectrum
bin_RLum.Data(object, bin_size.col = 1, bin_size.row = 1)

Value

[set_RLum]

An object from the class RLum.Data.Spectrum

[get_RLum]

1. A matrix with the spectrum values or

2. only the info object if info.object was set.

[names_RLum]

The names of the info objects

[bin_RLum.Data]

Same object as input, after applying the binning.

Arguments

object

get_RLum, names_RLum (required): an object of class RLum.Data.Spectrum

class

set_RLum; character (automatic): name of the RLum class to create.

originator

character (automatic): contains the name of the calling function (the function that produces this object); can be set manually.

.uid

set_RLum; character (automatic): sets an unique ID for this object using the internal C++ function create_UID.

.pid

set_RLum; character (with default): option to provide a parent id for nesting at will.

recordType

set_RLum; character: record type (e.g. "OSL")

curveType

set_RLum; character: curve type (e.g. "predefined" or "measured")

data

set_RLum; matrix: raw curve data. If data is of type RLum.Data.Spectrum, this can be used to re-construct the object. If the object is reconstructed, .uid, .pid and orginator are always taken from the input object

info

set_RLum list: info elements

info.object

get_RLum; character (optional): the name of the info object to be called

bin_size.col

integer (with default): set number of channels used for each bin, e.g. bin_size.col = 2 means that two channels are binned. Note: The function does not check the input, very large values mean a full column binning (a single sum)

bin_size.row

integer (with default): set number of channels used for each bin, e.g. bin_size.row = 2 means that two channels are binned. Note: The function does not check the input, very large values mean a full row binning (a single sum)

Methods (by generic)

• show(RLum.Data.Spectrum): Show structure of RLum.Data.Spectrum object

• set_RLum(RLum.Data.Spectrum): Construction method for RLum.Data.Spectrum object. The slot info is optional and predefined as empty list by default

• get_RLum(RLum.Data.Spectrum): Accessor method for RLum.Data.Spectrum object. The argument info.object is optional to directly access the info elements. If no info element name is provided, the raw curve data (matrix) will be returned

• names_RLum(RLum.Data.Spectrum): Returns the names info elements coming along with this curve object

• bin_RLum.Data(RLum.Data.Spectrum): Allows binning of RLum.Data.Spectrum data. Count values and values on the x-axis are summed-up; for wavelength/energy values the mean is calculated.

Slots

recordType

Object of class character containing the type of the curve (e.g. "TL" or "OSL")

curveType

Object of class character containing curve type, allowed values are measured or predefined

data

Object of class matrix containing spectrum (count) values. Row labels indicate wavelength/pixel values, column labels are temperature or time values.

info

Object of class list containing further meta information objects

Objects from the Class

Objects can be created by calls of the form set_RLum("RLum.Data.Spectrum", ...).

Class version
