Set the "how.measured" attribute

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

Usage

setHowMeasured(x, ...)

how_measured(x) <- value

# Default S3 method
setHowMeasured(x, how.measured, ...)

# S3 method for class 'generic_spct'
setHowMeasured(x, how.measured, ...)

# S3 method for class 'summary_generic_spct'
setHowMeasured(x, how.measured, ...)

# S3 method for class 'data.frame'
setHowMeasured(x, how.measured, ...)

# S3 method for class 'generic_mspct'
setHowMeasured(x, how.measured, ...)

Arguments

x

a R object.

...

Allows use of additional arguments in methods for other classes.

how.measured, value

a list or a character string.

Value

x modified by reference.

Methods (by class)

• setHowMeasured(default): default

• setHowMeasured(generic_spct): generic_spct

• setHowMeasured(summary_generic_spct): summary_generic_spct

• setHowMeasured(data.frame): data.frame

• setHowMeasured(generic_mspct): generic_mspct

Note

This function alters x itself by reference and in addition returns x invisibly. If x is not an object of a supported class, x is silently returned unchanged.
