Wrapper function that allows for optimization of multiple A/Ci or A/Q curves.

data |
observed assimilation data, which should be a data frame or matrix. The first column should contain a run or id. The second column should be observed net assimilation rate (μ mol m^{-2} s^{-1}). The third column should be the observed quantum flux (μ mol m^{-2} s^{-1}). The fourth column should be observed temperature of the leaf (Celsius). The fifth column should be the observed relative humidity in proportion (e.g. 0.7). An optional sixth column can contain atmospheric CO2. |
ID |
Optional vector with an alternative ID tothe one used in data for runs. The length shoudl be equal to the number of runs. |
ivmax |
Initial value for vmax. It can be a single value or a vector of length equal to the number of runs. |
ialpha |
Initial value for alpha. It can be a single value or a vector of length equal to the number of runs. |
iRd |
Initial value for vmax. It can be a single value or a vector of length equal to the number of runs. |
ikparm |
Initial value for vmax. It can be a single value or a vector of length equal to the number of runs. |
itheta |
Initial value for vmax. It can be a single value or a vector of length equal to the number of runs. |
ibeta |
Initial value for vmax. It can be a single value or a vector of length equal to the number of runs. |
curve.kind |
If |
op.level |
optimization level. If equal to 1
|
op.ci |
Whether to optimize intercellular CO2. Default is FALSE as 'fast-measured' light curves do not provide reliable values of Ci. |
verbose |
Whether to display output about convergence of each run. |

Used to supply additional arguments to
|
There are printing and plotting methods for the object
created by this function. The plotting function has an
argument that it is used to dsiplay either vmax or alpha
(i.e. parm=c('vmax','alpha')
). In both cases the
optimized value plus confidence intervals will be
displayed for each run.
