sjlabelled: Labelled Data Utility Functions

General

• Deprecated set_note() and get_note(), because there is already an R base function for this purpose: comment().
• Improved performance of functions, at the cost of removing support for the foreign package. sjlabelled now only supports labelled data from package haven.

Changes to functions

• get_term_labels() gets a prefix-argument to prefix the returned labels of categorical variable either with the related variable name or label.

Bug fixes

• Fix issues with retrieving incorrect labels from get_term_labels() for models that used unlabelled data in combination with other contrasts than the default option.
• get_dv_labels() no longer returns "NULL" for multivariate-response-models fitted with brms.
