Add an eFast simdesign to a nl object
Details
This function creates a simdesign S4 class which can be added to a nl object.
Variables in the experiment variable list need to provide a numeric distribution with min, max and qfun (e.g. list(min=1, max=4, qfun="qunif")).
The eFast simdesign uses the sensitivity package to set up a fast99 elementary effects sensitivity analysis, including a simobject of class fast99 and a input tibble for simulations. For details on method specific sensitivity analysis function parameters see ?fast99 Finally, the function reports a simdesign object.
