General setter function for RLum S4 class objects

The function provides a generalised access point for specific RLum objects. Depending on the given class, the corresponding method to create an object from this class will be selected. Allowed additional arguments can be found in the documentations of the corresponding RLum class:

Usage

set_RLum(class, originator, .uid = create_UID(), .pid = NA_character_, ...)

Arguments

class: character (required): name of the S4 class to create, must correspond to one of the RLum classes.
originator: character (automatic): contains the name of the calling function (the function that produces this object); can be set manually.
.uid: character (automatic): unique ID for this object, by default set using the internal C++ function create_UID.
.pid: character (with default): option to provide a parent id for nesting at will.
...: further arguments passed to the specific class method

Value

An object of the specified RLum class.

## produce a curve object with arbitrary curve values
object <- set_RLum(

## plot this curve object
