1	unique_value_labels(x, numeric_values = FALSE)

`x`	A variable to summarize.
`numeric_values`	Defaults to `FALSE` in which case the integer and numeric variables are no analyized. If `(TRUE)` it will create a similar character summary of the numeric variables.

unique_value_labels (x = c("apple", "strawberry", NA, "apple"))

#By default will not summarize numeric variables
unique_value_labels (x = c(1,2, NA, 3))

#But it is possible to create a similar summary of numeric variables.
unique_value_labels (x = c(1,2, NA, 3),
                     numeric_values = TRUE)
