Working with Labelled Data - cran.r-project.org Restore labels from subsetted data. The base subset() function drops label attributes (or vector attributes in general) when subsetting data. In the sjlabelled-package, there are handy functions to deal with this problem: copy_labels() and remove_labels(). copy_labels() adds back labels to a subsetted data frame based on the original data frame. And remove_labels() removes all label attributes.
