Executes an NLME shotgun covariate search

Executes an NLME shotgun covariate search

shotgunSearch(
  model,
  hostPlatform = NULL,
  params,
  covariateModel,
  runInBackground = FALSE,
  ...
)

Arguments

model

PK/PD model class object.

hostPlatform

Host definition for model execution. See hostParams. If missing, multicore local host with 4 threads is used.

params

Engine parameters. See engineParams. If missing, default parameters generated by engineParams(model) are used.

covariateModel

Covariate Effects Model providing the relationship between covariates and structural parameters to test (covariateModel(model)).

runInBackground

Set to TRUE to run in background and return prompt.

...

Additional arguments for hostParams or arguments available inside engineParams functions. If engineParams arguments are supplied through both params argument and additional argument (i.e., ellipsis), then the arguments in params will be ignored and only the additional arguments will be used with warning. If hostParams arguments are supplied through both the hostPlatform argument and the ellipses, values supplied to hostPlatform will be overridden by additional arguments supplied via the ellipses e.g., ....

Value

if runInBackground = FALSE, a data frame is returned with shotgun (all combinations given the covariate model) search results, i.e. "Overall" comma separated file. Otherwise the ShotgunNlmeJob class object is returned.
