• a .strict option has been added to set_variable_labels(), set_value_labels(), add_value_labels(), remove_value_labels(), set_na_values() and set_na_range(), allowing to pass values for columns not observed in the data (it could be useful for using a same list of labels for several data.frame sharing some variables) (#70)
• copy_labels() is less restrictive for non labelled vectors, copying variable label even if the two vectors are not of the same type (#71)
• a .strict option has been added to copy_labels() (#71)

  • look_for() now returns a tibble

  • a print method has been added for a clearer presentation of results in the console
  • use lookfor_to_long_format() to convert results with one row per factor level and per value label

labelled 2.0.0

BREAKING CHANGE

• Following version 2.0.0 of haven, labelled() and labelled_spss() now produce objects with class "haven_labelled" and "haven_labelled_spss", due to conflict between the previous "labelled" class and the "labelled" class used by Hmisc.
• A new function update_labelled() could be used to convert data imported with an older version of haven to the new classes.
