Update parameters working set with new values and value notes


Update parameters working set with new values and value notes


updateWorksetParameter(dbCon, defRs, worksetId, ...)



database connection


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


id of parameters working set, 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)

  • $subCount (optional) number of parameter sub-values, default: 1

  • subId (optional) parameter sub-value id, default: 0

  • $value (optional) parameter value it can be scalar value. vector or data frame size of $value must be equal to production of dimension sizes if data frame then it must have $dim0, $dim1,..., $value columns and each column length is equal to production of dimension sizes

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


That call allow you to update input parameter value and value notes in specific workset.

Parameter(s) can have can have multiple sub-values (by default only one value, no sub-values). If parameter have multiple sub-values then you can specify sub-value id as $subId (default =0).

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 unique name. To find set id by name use getWorksetIdByName call.

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

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


Return id of working set or 0L on error


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