haven 2.1.0

Improved labelling

labelled objects get pretty printing that shows the labels and NA values when inside of a tbl_df. Turn this behaviour off with behavior using option(haven.show_pillar_labels = FALSE) (#340, @gergness).

labelled() and labelled_spss() now allow NULL labels. This makes both classes more flexible, allowing you to use them for their other attributes (#219).

labelled() tests that value labels are unique (@larmarange, #364)

Minor improvements and bug fixes

• as_factor():

  • Is faster when input doesn't contain any missing values (@HughParsonage).
  • Added labelled method for backward compatbility (#414).
  • data.frame method now correctly passes ... along (#407, @zkamvar).

  values themselves (#401).
