The new class cps_spct has been added to package photobiology 0.6.2, together with corresponding functions and operators. A suitable plot() method has been added to package photobiologygg 0.3.1. The reason for adding one additional class is that counts-per-second from array spectrometers can be directly used in the calculation of spectral transmittance and spectral reflectance. Objects of this class are expected to be used to hold linearised spectral counts per second with a wavelength calibration applied but no pixel gain calibration applied. The need for this class became apparent during the development of a new version of package MayaCalc for data acquisition from spectrometers, but we think that it could be more generally useful.

Another addition to both packages is the new time.unit attribute value "exposure" with the meaning of the time-integrated response for the whole irradiation or exposure event.

The documentation was tidied-up in both packages, and the User Guides expanded.

NOTE: Sources, and Windows binaries for R 3.2.x, are now available in the repository.
