## S3 method for class 'colorSpec':
quantity(x)
quantity(x) <- value
## S3 method for class 'colorSpec':
type(x)quantity string; see Details.quantity returns the quantity of x
type returns the type of x, which depends only on the quantity.types, which are further divided into 14 valid quantities.
All of these are strings:
For type='light'
quantity = 'power' (radiometric), or 'photons/sec' (actinometric)
For type='responsivity.light'
quantity = 'power->electrical', 'power->neural', 'power->action',
'photons->electrical', 'photons->neural', or 'photons->action'
For type='material'
quantity = 'reflectance', 'transmittance', or 'absorbance'
For type='responsivity.material'
quantity = 'material->electrical', 'material->neural', or 'material->action'
For more explanation and examples of all these see
colorSpec-guide.pdf in the doc directory.
