Use meta data for variables from another GADSdat.

Transfer meta information from one GADSdat to another for one or multiple variables.

Usage

reuseMeta(
  GADSdat,
  varName,
  other_GADSdat,
  other_varName = NULL,
  missingLabels = NULL,
  addValueLabels = FALSE
)

Arguments

GADSdat: GADSdat object imported via eatGADS.
varName: Character vector with the names of the variables that should get the new meta data.
other_GADSdat: GADSdat object imported via eatGADS including the desired meta information. Can either be a GADSdat, an eatGADS data base or an all_GADSdat object.
other_varName: Character vector with the names of the variables in other_GADSdat that contain the meta data which should be copied.
missingLabels: How should meta data for missing values be treated? If NULL, missing values are transferred as all other labels. If "drop", missing labels are dropped (useful for imputed data). If "leave", missing labels remain untouched. If "only", all valid value labels are dropped.
addValueLabels: Should only value labels be added and all other meta information retained?

Value

Returns the original object with updated meta data.

Details

Transfer of meta information can mean substituting the complete meta information, only adding value labels, adding only "valid" or adding only "miss" missing labels. See the arguments missingLabels and addValueLabels for further details.
