spread.generic_mspct: Length of object in wavelength units

Description

A function that returns the spread (max(x) - min(x)) for R objects.

Usage

## S3 method for class 'generic_mspct':
spread(x, ..., idx = !is.null(names(x)))

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

spread(x, ...)

## S3 method for class 'default':
spread(x, ...)

## S3 method for class 'numeric':
spread(x, ...)

## S3 method for class 'waveband':
spread(x, ...)

Arguments

x

an R object

...

not used in current version

idx

logical whether to add a column with the names of the elements of spct

Value

• A numeric value equal to max(x) - min(x). In the case of spectral objects wavelength difference in nm. For any other R object, according to available definitions of min and max.

Methods (by class)

• generic_mspct: Method for "generic_mspct" objects.
• generic_spct: Method for "generic_spct" objects.
• default: Default method for generic function
• numeric: Default method for generic function
• waveband: Wavelength spread in nm.
