Class "RLum.Analysis"

Object class to represent analysis data for protocol analysis, i.e. all curves, spectra etc. from one measurements. Objects from this class are produced, by e.g. read_XSYG2R, read_Daybreak2R

Arguments
object

get_RLum: names_RLum, length_RLum, structure_RLum (required): an object of class '>RLum.Analysis

class

set_RLum character (required): name of the RLum class to be created

originator

set_RLum 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.

protocol

set_RLum character (optional): sets protocol type for analysis object. Value may be used by subsequent analysis functions.

records

set_RLum list (required): list of '>RLum.Analysis objects

info

set_RLum list (optional): a list containing additional info data for the object

set_RLum:

Returns an '>RLum.Analysis object.

record.id

get_RLum: numeric or logical (optional): IDs of specific records. If of type logical the entire id range is assumed and TRUE and FALSE indicates the selection.

recordType

get_RLum: character (optional): record type (e.g., "OSL"). Can be also a vector, for multiple matching, e.g., recordType = c("OSL", "IRSL")

curveType

get_RLum: character (optional): curve type (e.g. "predefined" or "measured")

RLum.type

get_RLum: character (optional): RLum object type. Defaults to "RLum.Data.Curve" and "RLum.Data.Spectrum".

get.index

get_RLum: logical (optional): return a numeric vector with the index of each element in the RLum.Analysis object.

drop

get_RLum: logical (with default): coerce to the next possible layer (which are RLum.Data-objects), drop = FALSE keeps the original RLum.Analysis

recursive

get_RLum: logical (with default): if TRUE (the default) and the result of the 'get_RLum' request is a single object this object will be unlisted, means only the object itself and no list containing exactly one object is returned. Mostly this makes things easier, however, if this method is used within a loop this might be undesired.

info.object

get_RLum: character (optional): name of the wanted info element

subset

get_RLum: expression (optional): logical expression indicating elements or rows to keep: missing values are taken as false. This argument takes precedence over all other arguments, meaning they are not considered when subsetting the object.

env

get_RLum: environment (with default): An environment passed to eval as the enclosure. This argument is only relevant when subsetting the object and should not be used manually.

fullExtent

structure_RLum; logical (with default): extents the returned data.frame to its full extent, i.e. all info elements are part of the return as well. The default value is FALSE as the data frame might become rather big.

...

further arguments passed to underlying methods

Value

get_RLum:

Returns:

  1. list of '>RLum.Data objects or

  2. Single '>RLum.Data object, if only one object is contained and recursive = FALSE or

  3. '>RLum.Analysis ojects for drop = FALSE

structure_RLum:

Returns '>data.frame showing the structure.

length_RLum

Returns the number records in this object.

names_RLum

Returns the names of the record types (recordType) in this object.

smooth_RLum

Same object as input, after smoothing

Note

The method structure_RLum is currently just avaiblable for objects containing '>RLum.Data.Curve.

Methods (by generic)

  • show: Show structure of RLum.Analysis object

  • set_RLum: Construction method for '>RLum.Analysis objects.

  • get_RLum: Accessor method for RLum.Analysis object.

    The slots record.id, recordType, curveType and RLum.type are optional to allow for records limited by their id (list index number), their record type (e.g. recordType = "OSL") or object type.

    Example: curve type (e.g. curveType = "predefined" or curveType ="measured")

    The selection of a specific RLum.type object superimposes the default selection. Currently supported objects are: RLum.Data.Curve and RLum.Data.Spectrum

  • structure_RLum: Method to show the structure of an '>RLum.Analysis object.

  • length_RLum: Returns the length of the object, i.e., number of stored records.

  • names_RLum: Returns the names of the '>RLum.Data objects objects (same as shown with the show method)

  • smooth_RLum: Smoothing of RLum.Data objects contained in this RLum.Analysis object zoo::rollmean or zoo::rollmedian. In particular the internal function .smoothing is used.

Slots

protocol

Object of class character describing the applied measurement protocol

records

Object of class list containing objects of class '>RLum.Data

Objects from the Class

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