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, ...)
# S3 method for waveband
clip_wl(x, range = NULL, ...)
# S3 method for list
clip_wl(x, range = NULL, ...)

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).

Value

A copy of x, most frequently of a shorter length, and never longer.

Methods (by class)

• default: Default for generic function

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

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

• waveband: Clip an object of class "waveband".

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