Get the

Function to read the "how.measured" attribute of an existing generic_spct, generic_mspct, summary_generic_spct, data.frame or a derived-class object.

Usage

getHowMeasured(x, ...)

how_measured(x, ...)

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

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

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

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

# S3 method for class 'generic_mspct'
getHowMeasured(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

character vector An object containing a 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 tibble with a column of character strings.
