boltzmann: Fits the traditional temperature centred Boltzmann function...

In padpadpadpad/TeamPhytoplankton: For studies into thermal adaptation

Description

Fits the traditional temperature centred Boltzmann function to data. If no high temperature inactivation is present then this allows for modelling of that data. Has a term in for whether the data is log transformed or not

Usage

boltzmann(ln.c, Ea, temp, Tc, log = c("Y", "N"))

Arguments

ln.c	Specific rate (of metabolism) at Tc
Ea	Activation energy
temp	Temperature in K
Tc	#standardization temperature (in ºC, arbitrary)
log	Whether or not the data is log transformed (potential values are "Y" or "N"). Defaults to "Y".

Examples

## The function is currently defined as
function (ln.c, Ea, temp, Tc, log = c("Y", "N")) 
{
    Tc <- 273.15 + Tc
    k <- 8.62e-05
    boltzmann.term <- ln.c + log(exp(Ea/k * (1/Tc - 1/temp)))
    exp.boltzmann.term <- ln.c * exp(Ea/k * (1/Tc - 1/temp))
    if (missing(log)) 
        return(boltzmann.term)
    if (log == "Y") 
        return(boltzmann.term)
    if (log == "N") 
        return(exp.boltzmann.term)
  }
