Clip head and/or tail of a spectrum
Clip head and tail of a spectrum based on wavelength limits, no interpolation used at range boundaries.
clip_wl(x, range, ...) ## Default S3 method: clip_wl(x, range, ...) ## S3 method for class 'generic_spct' clip_wl(x, range = NULL, ...) ## S3 method for class 'generic_mspct' clip_wl(x, range = NULL, ...) ## S3 method for class 'waveband' clip_wl(x, range = NULL, ...) ## S3 method for class 'list' clip_wl(x, range = NULL, ...)
x |
an R object. |
range |
a numeric vector of length two, or any other object for which
function |
... |
ignored (possibly used by derived methods). |
A copy of x, most frequently of a shorter length, and never
longer.
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").
The condition tested is wl >= range[1] & wl < (range[2] + 1e-13).
