Conversion methods for spectral photon irradiance into spectral energy irradiance and for spectral photon response into spectral energy response.

an R object.
a character string, one of "add", or "replace".
logical indicating if a new object will be created by reference or a new object returned.
not used in current version.
if TRUE, apply function in parallel, using parallel backend provided by foreach
a list of additional options passed into the foreach function when parallel computation is enabled. This is important if (for example) your code relies on external data or packages: use the .export and .packages arguments to supply them so that all cluster nodes have the correct environment set up for computing.
q2e(default): Default method
q2e(source_spct): Method for spectral irradiance
q2e(response_spct): Method for spectral responsiveness
q2e(source_mspct): Method for collections of (light) source spectra
q2e(response_mspct): Method for collections of response spectra
The converted spectral values are added to or replace the existing
spectral values depending on the argument passed to parameter
action. Addition is currently not supported for normalized spectra.
If the spectrum has been normalized with a recent version of package
'photobiology' the spectrum will be renormalized after conversion using the
same arguments as previously.
