linearize spectra and return modified object
# S3 method for colorSpec
linearize( x )linearize returns a colorSpec object with linear quantities.
a colorSpec object
If the quantity(x) is not 'absorbance'
then x is returned unchanged.
If the quantity(x) is 'absorbance'
then absorbance is converted to transmittance using
$$ transmittance = 10^{-absorbance} $$
Surprisingly, there does not seem to be a similar logarithmic version of reflectance.
Plots with log(responsivity) is somewhat common, but does not seem to have a separate name.
I have not seen log(radiometric power).
