normalize_range_arg

Several functions in this package and the suite accept a range argument
with a flexible syntax. To ensure that all functions and methods behave
in the same way this code has been factored out into a separate function.

Definitions of classes, methods, operators and functions for use
in photobiology and radiation meteorology and climatology. Calculation of
effective (weighted) and not-weighted irradiances/doses, fluence rates,
transmittance, reflectance, absorptance, absorbance and diverse ratios and
other derived quantities from spectral data. Local maxima and minima: peaks,
valleys and spikes. Conversion between energy-and photon-based units.
Wavelength interpolation. Astronomical calculations related solar angles and
day length. Colours and vision. This package is part of the 'r4photobiology'
suite, Aphalo, P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.

normalize_range_arg function

<dl><dt>arg.range</dt>
<dd>a numeric vector of length two, or any other object for
which function range() will return a range of wavelengths (nm).</dd>
<dt>wl.range</dt>
<dd>a numeric vector of length two, or any other object for which
function range() will return a range of wavelengths (nm), missing values
are not allowed.</dd>
<dt>trim</dt>
<dd>logical If TRUE the range returned is bound within
<code>wl.range</code> while if FALSE it can be broader.</dd></dl>

Arguments

Normalize a range argument into a true numeric range — normalize_range_arg

<dt>wl.range</dt>
<dd>a numeric vector of length two, or any other object for which
function range() will return a range of wavelengths (nm), missing values
are not allowed.</dd>


<dt>trim</dt>
<dd>logical If TRUE the range returned is bound within
<code>wl.range</code> while if FALSE it can be broader.</dd>
