clip_wl: Clip head and/or tail of a spectrum

Description

Clip head and tail of a spectrum based on wavelength limits, no interpolation used at range boundaries.

Usage

clip_wl(x, range, ...)
# S3 method for default
clip_wl(x, range, ...)
# S3 method for generic_spct
clip_wl(x, range = NULL, ...)
# S3 method for generic_mspct
clip_wl(x, range = NULL, expand = TRUE, ...)
# S3 method for waveband
clip_wl(x, range = NULL, ...)
# S3 method for list
clip_wl(x, range = NULL, ...)

Value

a spectrum object or a collection of spectral objects of the same class as x with wavelength heads and tails clipped.

Arguments

x

an R object.

range

a numeric vector of length two, or any other object for which function range() will return range of wavelengths expressed in nanometres.

...

ignored (possibly used by derived methods).

expand

logical Expand or not members containing spectra in long form.

Methods (by class)

• clip_wl(default): Default for generic function

• clip_wl(generic_spct): Clip an object of class "generic_spct" or derived.

• clip_wl(generic_mspct): Clip an object of class "generic_mspct" or derived.

• clip_wl(waveband): Clip an object of class "waveband".

• clip_wl(list): Clip a list (of objects of class "waveband").
