Add a morris elementary effects simdesign to a nl object
nl object with a defined experiment
morris design type
number of parameter levels
morris r value
morris grid jump value
number of seeds for this simulation design
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 morris simdesign uses the sensitivity package to set up a morris elementary effects sensitivity analysis, including a simobject of class morris and a input tibble for simulations. For details on method specific sensitivity analysis function parameters see ?morris Finally, the function reports a simdesign object.
# To attach a simdesign, a nl object needs to be created first (see ?nl). # For this example, we load a nl object from test data. nl <- nl_morris nl@simdesign <- simdesign_morris(nl=nl, morristype="oat", morrislevels=4, morrisr=20, morrisgridjump=2, nseeds=3) #> Creating morris simulation design #> Warning: keeping 16 repetitions out of 20
