Convert numeric vectors into factors associated value labels

This function converts numeric variables into factors, and uses associated value labels as factor levels.

numeric_to_factor(x, n = 4)

`x`	A data frame.
`n`	Numeric, indicating the maximum amount of unique values in `x` to be considered as "factor". Variables with more unique values than `n` are not converted to factor.

If x is a labelled vector, associated value labels will be used as level. Else, the numeric vector is simply coerced using as.factor().

x, with numeric values with a maximum of n unique values being converted to factors.
