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").
