skylight_rcpp

Calculates sky illuminance values faster. This function
should not be called independently and the formal R
skylight() function should be used with the parameter
fast = TRUE!

A tool to calculate sky illuminance values (in lux) for both sun and moon. The
model is a translation of the Fortran code by Janiczek and DeYoung (1987)
