# make toy demographic (gender, raceth, etc.) data set
set.seed(555)
df <- make_demo_data(n = 1000) # another labelr:: function
# let's add variable VALUE labels for variable "race"
df <- add_val_labs(df,
  vars = "raceth", vals = c(1:7),
  labs = c("White", "Black", "Hispanic", "Asian", "AIAN", "Multi", "Other"),
  max.unique.vals = 50
)

check_labs_att(df) # is any valid labelr lab(el) attribute present?
check_labs_att(df, "val.labs.race") # "race" lab specifically TRUE
