photobiology (version 0.9.16)

tag: Tag a spectrum

Description

Spectra are tagged by adding variables and attributes containing color definitions, labels, and a factor following the wavebands given in w.band.

Usage

tag(x, ...)
# S3 method for default
tag(x, ...)
# S3 method for generic_spct
tag(x, w.band = NULL,
  wb.trim = getOption("photobiology.waveband.trim", default = TRUE),
  use.hinges = TRUE, short.names = TRUE, byref = FALSE, ...)
# S3 method for generic_mspct
tag(x, w.band = NULL,
  wb.trim = getOption("photobiology.waveband.trim", default = TRUE),
  use.hinges = TRUE, short.names = TRUE, byref = FALSE, ...)

Arguments

x

an R object

...

not used in current version

w.band

waveband or list of waveband objects The waveband(s) determine the region(s) of the spectrum that are tagged

wb.trim

logical Flag telling if wavebands crossing spectral data boundaries are trimmed or ignored

use.hinges

logical Flag indicating whether to use hinges to reduce interpolation errors

short.names

logical Flag indicating whether to use short or long names for wavebands

byref

logical Flag indicating if new object will be created by reference or by copy of x

Methods (by class)

• default: Default method for generic

• generic_spct: Tag one of generic_spct, and derived classes including source_spct, filter_spct, reflector_spct, object_spct, and response_spct.

• generic_mspct: Tag one of generic_mspct, and derived classes including source_mspct, filter_mspct, reflector_mspct, object_mspct, and response_mspct.
