getFilterProperties: Get the "filter.properties" attribute

In photobiology: Photobiological Calculations

Get the "filter.properties" attribute

Description

Function to read the "filter.properties" attribute of an existing filter_spct or a filter_mspct.

Usage

getFilterProperties(x, return.null, ...)

filter_properties(x, return.null, ...)

## Default S3 method:
getFilterProperties(x, return.null = FALSE, ...)

## S3 method for class 'filter_spct'
getFilterProperties(x, return.null = FALSE, ...)

## S3 method for class 'summary_filter_spct'
getFilterProperties(x, return.null = FALSE, ...)

## S3 method for class 'generic_mspct'
getFilterProperties(x, return.null = FALSE, ..., idx = "spct.idx")

Arguments

x	a filter_spct object
return.null	logical If true, NULL is returned if the attribute is not set, otherwise the expected list is returned with all fields set to NA.
...	Allows use of additional arguments in methods for other classes.
idx	character Name of the column with the names of the members of the collection of spectra.

Value

a list with fields named "Rfr.constant" [/1], "thickness" [m] and "attenuation.mode". If the attribute is not set, and return.null is FALSE, a list with fields set to NA is returned, otherwise, NULL.

Methods (by class)

• getFilterProperties(default): default

• getFilterProperties(filter_spct): generic_spct

• getFilterProperties(summary_filter_spct): summary_generic_spct

• getFilterProperties(generic_mspct): filter_mspct

Note

The method for collections of spectra returns the a tibble with a column of lists.
