⚠️There's a newer version (0.6.1-1) of this package.Take me there.

R package 'photobiologyPlants'

Package 'photobiologyPlants' provides pre-defined functions for quantifying visible ('VIS') and ultraviolet ('UV') radiation in relation to the photoreceptors 'Phytochromes', 'Cryptochromes', and 'UVR8' which are present in plants. It also includes data sets on the optical properties of plants.

This package is part of a suite of R packages for photobiological calculations described at the r4photobiology web site.
