merge_attributes

merge_attributes.default

merge_attributes.generic_spct

Merge attributes from <code>x</code> and <code>y</code> and copy them to <code>z</code>.
Methods defined for spectral objects of classes from package 'photobiology'.

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>.

merge_attributes function

<dl><dt>x, y, z</dt>
<dd>R objects. Objects <code>x</code> and <code>y</code> must be of the same class,
<code>z</code> must be an object with a structure valid for this same class.</dd>
<dt>which</dt>
<dd>character Names of attributes to copy, if NULL all those
relevant according to the class of <code>x</code> are used as default,</dd>
<dt>which.not</dt>
<dd>character Names of attributes not to be copied. The
names passed here are removed from the list for <code>which</code>, which
is most useful when we want to modify the default.</dd>
