Safe manipulation of object metadata

Description

Generic functions for manipulation of metadata in Risoe.BINfileData, RLum.Analysis and RLum.Data objects.

Usage

add_metadata(object, ...) <- value

rename_metadata(object, ...) <- value

replace_metadata(object, ...) <- value

Arguments

object	(required) object to manipulate
...	further arguments passed to the specific class method
value	the value to be assigned

Examples

## load example data
data(ExampleData.BINfileData, envir = environment())

## show data
CWOSL.SAR.Data

## add a new field
add_metadata(CWOSL.SAR.Data,
             info_element = "INSTITUTE") <- "Heidelberg University"

## rename a field
rename_metadata(CWOSL.SAR.Data,
                info_element = "INSTITUTE") <- "INSTITUTION"

## replace all LTYPE to RSL
## but only for the first position
replace_metadata(
 object = CWOSL.SAR.Data,
 info_element = "LTYPE",
 subset = (POSITION == 1)) <- "RSL"

## replacing a field with NULL allows to remove that field
replace_metadata(CWOSL.SAR.Data,
                 info_element = "PREVIOUS") <- NULL

## show the modified data
CWOSL.SAR.Data
