extractManipData(obj, ignoreKeyVars = FALSE, ignorePramVars = FALSE,
  ignoreNumVars = FALSE, ignoreGhostVars = FALSE, ignoreStrataVar = FALSE,
  randomizeRecords = "no")

`obj`	object of class `sdcMicroObj-class`
`ignoreKeyVars`	If manipulated KeyVariables should be returned or the unchanged original variables
`ignorePramVars`	if manipulated PramVariables should be returned or the unchanged original variables
`ignoreNumVars`	if manipulated NumericVariables should be returned or the unchanged original variables
`ignoreGhostVars`	if manipulated Ghost (linked) Variables should be returned or the unchanged original variables
`ignoreStrataVar`	if manipulated StrataVariables should be returned or the unchanged original variables
`randomizeRecords`	(logical) specifies, if the output records should be randomized. The following options are possible: 'no'default, no randomization takes place 'simple'records are just randomly swapped. 'byHH'if slot 'hhId' is not `NULL`, the clusters defined by this variable are randomized across the dataset. If slot 'hhId' is `NULL`, the records or the dataset are randomly changed. 'withinHH'if slot 'hhId' is not `NULL`, the clusters defined by this variable are randomized across the dataset and additionally, the order of records within the clusters are also randomly changed. If slot 'hhId' is `NULL`, the records or the dataset are randomly changed.

a data.frame containing the anonymized data set
