Provides access to the 'PlanScore' Application Programming Interface 
    (<https://github.com/PlanScore/PlanScore/blob/main/API.md>) for scoring redistricting
    plans. Allows for upload of plans from block assignment files and shape files. 
    For shapes in memory, such as from 'sf' or 'redist', it processes them to save
    and upload. Includes tools for tidying responses and saving output from the 
    website.

Coupled leaf gas exchange model, A-Ci curve simulation and
    fitting, Ball-Berry stomatal conductance models, 
    leaf energy balance using Penman-Monteith, Cowan-Farquhar
    optimization, humidity unit conversions.

Provides wrapping functions to add to capabilities to 'plantecophys' 
    (Duursma, 2015, <doi:10.1371/journal.pone.0143346>). Key added capabilities 
    include temperature responses of mesophyll conductance (gm, gmeso), apparent 
    Michaelis-Menten constant for rubisco carboxylation in air (Km, Kcair),and
    photorespiratory CO2 compensation point (GammaStar) for fitting A-Ci or A-Cc
    curves for C3 plants (for temperature responses of gm, Km, & GammaStar,  see 
    Bernacchi et al., 2002, <doi:10.1104/pp.008250>; for theory on fitting A-Ci 
    or A-Cc curves, see Farquhar et al., 1980; <doi:10.1007/BF00386231>, von 
    Caemmerer, 2000, ISBN:064306379X; Ethier & Livingston, 2004 
    <doi:10.1111/j.1365-3040.2004.01140.x>; and Gu et al., 2010, 
    <doi:10.1111/j.1365-3040.2010.02192.x>). Includes the ability to fit the 
    Arrhenius and modified Arrhenius temperature response functions (see Medlyn 
    et al., 2002, <doi:10.1046/j.1365-3040.2002.00891.x>) for maximum rubisco 
    carboxylation rates (Vcmax) and maximum electron transport rates (Jmax) (see
    Farquhar et al., 1980; <doi:10.1007/BF00386231>).

Functions tailored for scientific and student communities involved in plant science research. Functionalities encompass estimation chlorophyll content according to Arnon (1949) <doi:10.1104/pp.24.1.1>, determination water potential of Polyethylene glycol(PEG)6000 as in Michel and Kaufmann (1973) <doi:10.1104/pp.51.5.914>  and functions related to estimation of yield related indices like Abiotic tolerance index as given by Moosavi et al.(2008)<doi:10.22059/JDESERT.2008.27115>, Geometric mean productivity (GMP) by Fernandez (1992) <ISBN:92-9058-081-X>, Golden Mean by Moradi et al.(2012)<doi:10.14207/ejsd.2012.v1n3p543>, HAM by Schneider et al.(1997)<doi:10.2135/cropsci1997.0011183X003700010007x>,MPI and TOL by Hossain etal., (1990)<doi:10.2135/cropsci1990.0011183X003000030030x>, RDI by Fischer et al.
