Pfr_Ptot | R Documentation |
A method implemented for objects of different classes.
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, ...)
x |
an R object |
... |
not used |
spct.out |
logical Flag indicating if the returned object should be of
class |
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
Pfr_Ptot(default)
: Default for generic function
Pfr_Ptot(numeric)
: Specialization for numeric
Pfr_Ptot(source_spct)
: Specialization for source_spct
