The following functions are the main tools in plantecophys:

  1. fitaci (and fitaci) fits A-Ci curves to data.

  2. Photosyn can be used to simulate A-Ci curves (or Aci), and simulate from a coupled leaf gas exchange model.

  3. fitBB fits Ball-Berry-type stomatal conductance models to data.

  4. FARAO is an implementation of a numeric solution to Cowan-Farquhar optimization of stomatal conductance.

  5. RHtoVPD converts relative humidity to vapour pressure deficit (and more similar functions on that help page).

The package also includes the following example datasets:

  1. acidata1 A dataset with a single A-Ci curve.

  2. manyacidat A dataset with many A-Ci curves.
