Convert luxR reflectance to a photobiology reflector_spct

Bridges a reflectance lux_spectrum into photobiology as a reflector_spct. luxR already constrains reflectance to [0, 1], so values map onto Rfr directly.

Usage

as_reflector_spct(x, ...)

# S3 method for class 'lux_spectrum'
as_reflector_spct(x, Rfr.type = NULL, strict.range = TRUE, ...)

# S3 method for class 'list'
as_reflector_spct(x, ...)

Arguments

x

A reflectance lux_spectrum, or a (named) list of them.

...

Passed to photobiology::reflector_spct().

Rfr.type

Either "total" or "specular". Defaults to x$meta$Rfr_type; an error is raised if neither is supplied.

strict.range

Passed to photobiology::reflector_spct(). Defaults to TRUE.

Value

A photobiology reflector_spct.

Details

Rfr.type is required. Whether a reflectance is total or specular is a fact about how it was measured, which luxR does not otherwise carry; defaulting it would silently mislabel the measurement inside another package's ecosystem. Record it once in the spectrum's meta$Rfr_type to have it picked up automatically.

  r <- as_reflector_spct(my_reflectance, Rfr.type = "total")
