Pfr_Ptot(x, ...)

## Default S3 method:
Pfr_Ptot(x, ...)

## S3 method for class 'numeric'
Pfr_Ptot(x, spct.out = length(x) > 20, ...)

## S3 method for class 'source_spct'
Pfr_Ptot(x, ...)

Arguments

x

an R object

...

not used

spct.out

logical Flag indicating if the returned object should be of class response_spct instead of numeric.

Value

If x is numeric, giving wavelengths (nm), a vector of numeric values giving the unitless photon ratio at each wavelength or a generic_spct object with the wavelength values sorted in ascending order and the corresponding Pfr_Ptot values in column s.q.response.

If x is a source_spct object, a single numeric value giving the unitless photon ratio
