UVcalc is updated to version 1.0.6. The changes are minor. Added a few more functions, including one additional action spectrum. Functions from earlier versions remain unchanged in their functionality. Please, report any bug you may find. Thanks!
If you have not heard about it yet, UVcalc is a package for the R system for statistics, that can be used for calculating action spectra, unweighted and effective UV doses, and some photon ratios frequently used in plant photobiology.
