Hello! I'm interested to fit parameters (to data) in a grid-based (individual) model. If I understood well, simecol library has the fitOdeModel function but it is only suited to odeModels (differential equation). Alternatively, FME package has several functions able to perform this procedure but all examples are for differential eq. models. It is mentioned in the that such functions could also be used for other kind of models. Could thus be used for grid-based ones? If that, could be used even the model does not follow the simecol syntax? Thanks for your help! Javier -- ########################################################## Javier Rodríguez Pérez Dep.
