dBaranyi

Microbial growth model as defined in Baranyi and Roberts (1994). It has
been implemented according to the requirements of
<code>deSolve::ode()</code>. For consistency in the function for isothermal growth,
calculations are done assuming the user input for mu is in log10 scale. In other words,
the input is multiplied by ln(10).

Modelling of population growth under static and dynamic environmental conditions.
Includes functions for model fitting and making prediction under isothermal and
dynamic conditions. The methods (algorithms & models) are based on
predictive microbiology (See Perez-Rodriguez and Valero (2012, ISBN:978-1-4614-5519-6)).
