Records whether every bundled species has a supported default chromatic and achromatic model. Unsupported combinations remain explicit rather than being inferred from receptor-role labels.
Format
A data frame with 16 rows and 5 columns:
- species
Scientific name matching
species_sensitivities.- channel_role
Either
"chromatic"or"achromatic".- status
Either
"supported"or"unavailable".- reason
Evidence summary or reason no default is available.
- source
Literature citation or explicit package review decision.
Details
Every supported row must correspond to exactly one default in
species_channels. Every unavailable row must have no default.
Dataset generation and runtime validation enforce this invariant.
Examples
data(species_channel_support)
subset(species_channel_support, species == "Homo sapiens")
#> species channel_role status
#> 1 Homo sapiens chromatic supported
#> 2 Homo sapiens achromatic unavailable
#> reason
#> 1 Validated S M and L cone opponent set
#> 2 No adaptation-specific photopic or scotopic default is encoded
