modifyModel

Allows the starting values for parameters associated with
a model to be updated with the values found in fitting the model. That
is, a model is specified with <code>initModel</code>. Then <code>fitModel</code>
is used to optimize the starting values for parameters. <code>modifyModel</code>
allows modification of the starting values in the model specification
with the optimized values found via <code>fitModel</code>.

A problem solving environment (PSE) for fitting separable
nonlinear models to measurements arising in physics and chemistry
experiments, as described by Mullen & van Stokkum (2007)
<doi:10.18637/jss.v018.i03> for its use in fitting time resolved
spectroscopy data, and as described by Laptenok et al. (2007)
<doi:10.18637/jss.v018.i08> for its use in fitting Fluorescence
Lifetime Imaging Microscopy (FLIM) data, in the study of Förster
Resonance Energy Transfer (FRET). `TIMP` also serves as the
computation backend for the `GloTarAn` software, a graphical user
interface for the package, as described in Snellenburg et al. (2012)
<doi:10.18637/jss.v049.i03>.

modifyModel function

<dl> <dt>model</dt>
<dd>an object of class <code>dat</code> returned by <code>initModel</code>;
 if this argument is of <code>length(0)</code>, which is the default, then the
 last model fit is used (which is found in the global variable
 <code>.currModel@model</code>)</dd> <dt>newest</dt>
<dd>an object of class <code>theta</code> containing new parameter
 estimates; if this argument is of <code>length(0)</code>, which is the default,
 then the parameter estimates associated with dataset 1 in the last model fit
 are used (which are found in
 the global variable <code>.currTheta[[1]]</code>)</dd> <dt>exceptslots</dt>
<dd>a vector of character vector of slot names whose
 corresponding slots are to be left out of the update</dd></dl>
