photobiologyPlants 0.6.2

• Add function PQ_redox_state() and data object PS1_PS2_k.spct for estimation of the redox state of the plastoquinone pool of photosynthesis in Arabidopsis with the model in Mattila et al. (2020).
• Add specialization of Pfr_Ptot() for collections of spectra.
• Update xPAR_irrad() to support multiple spectra in long form and forcing of data frame output for a single spectrum.
• Add functions rs_from_size(), gs_from_size(), gs_water_from_size() and gs_CO2_from_size(). These functions make it possible to estimate stomatal conductance from anatomical measurements on the epidermis of leaves, using equations from Monteith and Unsworth (2008).
• Add functions gs_c_from_gs_w(), gs_w_from_gs_c(), gs_vol2mol() and gs_mol2vol() for interconverting stomatal conductance values.
• Add functions D_water(), D_CO2(), and molar_vol() for computing diffusion coefficients for water vapour and CO2, and the molar volume of an ideal gas from temperature and pressure.

photobiologyPlants 0.6.1-1

Depend on ‘photobiology’ (>= 0.14.0) and ‘ggspectra’ (>= 0.3.17) to avoid errors in vignette example and in users’ code.

photobiologyPlants 0.6.1

In recent years a few new photon ratios and irradiances have been proposed to describe light spectra in relation to plants responses. This update adds functions to easily compute them.

• Track enhancements in packages ‘photobiology’ (>= 0.14.0) and ‘photobiologyWavebands’ (>= 0.5.3).
• Add parameter na.rm and checks for NAs and low wavelength resolution to the Pfr_Ptot() method for source_spct objects.
• Add methods xPAR_irrad() to compute extended photosynthetically active radiation photon irradiance in constrained (xPAR) and unconstrained (ePAR), and their PAR and far-red (FR) components.
• Add function FR_RpFR(), R_RpFR(), FR_PAR(), FR_ePAR(), UVA1_UVA(), UVA2_UVA() and update all functions for computing photon ratios to forward additional named arguments to q_ratio().
• Breaking: Change default in R_FR() from "Smith10" into "Smith20“.
• Collect the documentation of all functions for computing different photon ratios into a single help page.

photobiologyPlants 0.6.0

• Rebuild data objects with photobiology 0.10.16.
• The repository with the source of the package was relocated to GitHub.

photobiologyPlants 0.4.2

• CODE BREAKING: Some data objects have been renamed and consequently old scripts may need minor edits.
• DATA CHANGES: Spectral data has increased wavelength resolution.
• Add spectral absorbance data for cryptochromes 1 and 3, phototropins 1 and 2, ZTL protein, eight carotenoids and chlorophylls a and b.
• Add spectral fluorescence emission data for chlorophylls a and b.

photobiologyPlants 0.4.0

• Rebuild data objects with photobiology 0.9.9, after updating scripts to create collections of spectra instead of separate objects for related data sets.
• Add functions for frequently used photon ratios.
• Remove some redundant phytochrome-related functions.

photobiologyPlants 0.3.3

Compatibility update for photobiology 0.9.1 and ggplot2 2.0.0. Use ggspectra instead of photobiologygg.
