checkModel tries to establish the simulation file for a given model

This function returns the model name, with some additional comments about the file

Usage

checkModel(modelName, modelFile = NULL)

Arguments

modelName: a string
modelFile: a string, if the model file is different from "modelName.R". If the file name ends in .c, the c source will be compiled to a shared library.

Value

modelName with an additional comment about which file to use for simulations

Details

As an alternative to this function, it is sufficient to write

modelName <- "test_ode_model"             # or some other model name
comment(modelName) <- "test_ode_model.so"

This function will not attempt to find a model file, other than in the current directory. But, checkModel will compile a GSL compatible C source file into a shared object if modelFile ends with .c and stop if that doesn't work. The compiler is called using a system call, which may be incorrect for your system -- if this funciton fails, you'll have to make the shared library of the model using the correct compiler and options for your system.

In any case, this function stops execution if the model file doesn't exist, because simulations are not possible.
