bind: Combine colorSpec Objects
Description
Take a sequence of colorSpec objects and combine their spectra - if they all
have the same wavelength and quantityUsage
## S3 method for class 'colorSpec':
bind( \ldots )
Value
bind returns a colorSpec object, or NULL in case of ERROR. If the bind is
successful, the number of spectra in the output object is the sum of the number of spectra
in the input objects.
Details
The organization of the returned object is the most complex of those in the input list,
where the order of complexity is:
'matrix' < 'df.col' < 'df.row'
If the selected organization is 'df.row' the extradata is combined using merge.
The metadata of the returned object is copied from the first object in the input list.
