subset2mspct

a generic_spct object or a derived class, or a data frame

member.class

character Name of column containing data to be copied
unchanged to each spct object

idx.var

logical Flag indicating whether to drop or keep idx.var in
the collection members.

drop.idx

integer Number of 'virtual' columns in data

ncol

logical If <code>ncol > 1</code> how to read in the data

byrow

Convert a data frame object or spectral object into a collection
  of soectra object of the corresponding class. For data frames converting
  numeric columns other than wavelength into individual spct objects.

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'. Conversion between energy- and photon-based units. Wavelength
    interpolation. Astronomical calculations related solar angles and day
    length. Colours and vision.

subset2mspct: Convert 'long' or tidy spectral data into a collection of spectra
