Variable labels can be created using ff_label. Some functions
strip variable labels (variable attributes), e.g. forcats::fct_recode.
Use this function to create a vector of variable labels from a data frame.
Then use ff_relabel to relabel variables in data frame.
extract_variable_label(.data)Dataframe containing labelled variables.
