1d:T747,# Extract and modify variables from population or sample data stored in an object of class `simPopObj-class`. Using `samp` `samp<-` it is possible to extract or rather modify variables of the sample data within slot `data` in slot `sample` of the `simPopObj-class`-object. Using `pop` `pop<-` it is possible to extract or rather modify variables of the synthetic population within in slot `data` in slot `sample` of the `simPopObj-class`-object. methods ## Arguments - `obj`: An object of class `simPopObj-class` - `var`: variable name or index for the variable in slot 'samp' of object with the slot name to be accessed. If `NULL`, the entire dataset (sample or population) is returned. - `value`: Content replacing whatever the variable in slot `var` in `obj` currently holds. ## Returns Returns an object of class `simPopObj-class` with the appropriate replacement. ## Examples ```r data(eusilcS) inp <- specifyInput(data=eusilcS, hhid="db030", hhsize="hsize", strata="db040", weight="db090") simPopObj <- simStructure(data=inp, method="direct", basicHHvars=c("age", "rb090")) ## get/set variables in sample-object of simPopObj head(samp(simPopObj, var="age")) samp(simPopObj, var="newVar") <- 1 head(samp(simPopObj, var="newVar")) ## deleting is also possible samp(simPopObj, var="newvar") <- NULL head(samp(simPopObj, var="newvar")) ## extract multiple variables head(samp(simPopObj, var=c("db030","db040"))) ## get/set variables in pop-object of simPopObj head(pop(simPopObj, var="age")) pop(simPopObj, var="newVar") <- 1 head(pop(simPopObj, var="newVar")) ## deleting is also possible pop(simPopObj, var="newvar") <- NULL head(pop(simPopObj, var="newvar")) ## extract multiple variables head(pop(simPopObj, var=c("db030","db040"))) ``` ## See Also `simPopObj-class`,`pop`, `pop<-`, `samp<-`, `manageSimPopObj` ## Author(s) Bernhard Meindl
