A method specialization that returns the wavelength maximum [\(nm\)] from
objects of classes waveband or of class generic_spct or
derived.
Usage
wl_max(x, na.rm = FALSE)
# S3 method for class 'waveband'
max(..., na.rm = FALSE)
# S3 method for class 'generic_spct'
max(..., na.rm = FALSE)
# S3 method for class 'generic_mspct'
max(..., na.rm = FALSE, idx = "spct.idx")
Arguments
- x
generic_spct, generic_mspct or waveband object.
- na.rm
ignored
- ...
numeric, waveband or generic_spct arguments.
- idx
character Name of the column with the names of the members of the
collection of spectra.
Value
a length-one vector for individual objects or numeric vectors
or a data frame for collections of spectra.
Examples
max(sun.spct)
#> [1] 800
wl_max(sun.spct)
#> [1] 800
