In photobiology: Photobiological Calculations

Get the "when.measured" attribute

Description

Function to read the "when.measured" attribute of an existing generic_spct or a generic_mspct.

Usage

getWhenMeasured(x, ...)

when_measured(x, ...)

## Default S3 method:
getWhenMeasured(x, ...)

## S3 method for class 'generic_spct'
getWhenMeasured(x, ...)

## S3 method for class 'summary_generic_spct'
getWhenMeasured(x, ...)

## S3 method for class 'generic_mspct'
getWhenMeasured(x, ..., idx = "spct.idx")

Arguments

x	a generic_spct object
...	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

POSIXct An object with date and time.

Methods (by class)

• getWhenMeasured(default): default

• getWhenMeasured(generic_spct): generic_spct

• getWhenMeasured(summary_generic_spct): summary_generic_spct

• getWhenMeasured(generic_mspct): generic_mspct

Note

If x is not a generic_spct or an object of a derived class NA is returned.

The method for collections of spectra returns the a tibble with the correct times in TZ = "UTC".
