copyWorksetParameterFromRun {openMpp}R Documentation

Copy parameters to working set from existing model run

Description

Copy parameters to working set from existing model run with new value notes

Usage

copyWorksetParameterFromRun(dbCon, defRs, worksetId, baseRunId, ...)

Arguments

dbCon

database connection

defRs

model definition: database rows describing model input parameters and output tables

worksetId

id of parameters working set, must be positive integer

baseRunId

id of model run results, must be positive integer

...

list of parameters value and value notes.

Each element is also a list of $name, $subCount, $subId, $value, $txt:

  • $name parameter name (character)

  • $txt (optional) workset parameter text: data frame with $lang = language code and $note = value notes

Details

That call allow you to add a copy of input parameter value from existing model run into workset and update value notes.

Parameter(s) can have can have multiple sub-values (by default only one value, no sub-values). All parameter sub-values are copied from existing model run.

Workset is a working set of model parameters and can be a full set, which include values of all model parameters or subset and include only some parameters.

Each model must have "default" workset. Default workset is a first workset of the model with set_id = min(set_id) for that model. Default workset always include ALL model parameters (it is a full set).

If you want to create new workset as a full set of model parameters then you must pass ALL model parameters into createWorkset through ... argument list.

If you already have result of model run in your database and want to modify only some input parameters (subset) then call createWorksetBasedOnRun in order to create workset using parameters from previous model run and supply some new values.

You can create subset of model parameters ONLY based on existing run results. Otherwise you have to pass ALL (full set) of parameters in order to create workset.

Each workset has unique set id (positive integer) and also may have a name. To find set id by name use getWorksetIdByName call.

Working set must be not read-only in order to add parameters by copyWorksetParameterFromRun. And working set must be read-only to run the model, so, typically you want to wrap copyWorksetParameterFromRun by setReadonlyWorkset calls.

You must use getModel function in order to find model definition defRs.

Value

Return id of working set or 0L on error

Note

To run examples you must have modelOne database modelOne.sqlite in current directory

  # get model by name: use such call if you have only one version of the model
  defRs <- getModel(theDb, "modelOne")
  
  #
  # create new working set
  # for all parameters use previous model run with id = 101 
  #
  setId <- createWorksetBasedOnRun(theDb, defRs, 101L, inputSet)
  if (setId <= 0L) stop("workset creation failed: ", defRs$modelDic$model_name, " ", defRs$modelDic$model_digest)
  
  #
  # copy ageSex parameter value from model run with id = 102
  #
  copyWorksetParameterFromRun(theDb, defRs, setId, 102L, ageSex)
  
  # make workset read-only in order to run the model
  setReadonlyWorkset(theDb, defRs, TRUE, setId)
  
  dbDisconnect(theDb)
  #
  # you can run the model now with new ageSex parameter value
