%description
Calculation routines based on the FOCUS Kinetics Report (2006, 2014).
Includes a function for conveniently defining differential equation
models, model solution based on eigenvalues if possible or using numerical
solvers.  If a C compiler (on windows: 'Rtools') is installed,
differential equation models are solved using automatically generated C
functions. Heteroscedasticity can be taken into account using variance by
variable or two-component error models as described by Ranke and Meinecke
(2018) <doi:10.3390/environments6120124>.  Hierarchical degradation models
can be fitted using nonlinear mixed-effects model packages as a back end
as described by Ranke et al. (2021) <doi:10.3390/environments8080071>.
Please note that no warranty is implied for correctness of results or
fitness for a particular purpose.
