In photobiology: Photobiological Calculations

Get the "how.measured" attribute

Description

Method to read the "how.measured" attribute of an R object.

Usage

getHowMeasured(x, ...)

how_measured(x, ...)

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

## S3 method for class 'generic_spct'
getHowMeasured(x, ..., simplify = FALSE)

## S3 method for class 'summary_generic_spct'
getHowMeasured(x, ..., simplify = FALSE)

## S3 method for class 'data.frame'
getHowMeasured(x, ..., simplify = FALSE)

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

Arguments

x	an R object.
...	Allows use of additional arguments in methods for other classes.
simplify	logical If all members share the same attribute value return one copy instead of a data.frame.
idx	character Name of the column with the names of the members of the collection of spectra.

Value

character vector An object containing a verbal description of the data.

Methods (by class)

• getHowMeasured(default): default

• getHowMeasured(generic_spct): generic_spct

• getHowMeasured(summary_generic_spct): summary_generic_spct

• getHowMeasured(data.frame): data.frame

• getHowMeasured(generic_mspct): generic_mspct

Note

The method for collections of spectra returns the a data frame with a column of character strings.
