in `boxcox3()`, consider `labile_data` argument, cf `retriever()`

Not quite there yet—different to retriever() as X not a DF. Needs further consideration…

OK, using eval_tidy() to resolve quosure, not data mask

Nevertheless, code improved: –

boxcox3 <- function(x, labile_data = TRUE) {
    if (labile_data) {
        x <- enquo(x)

        function(lambda) {
            eval_tidy(
                if (lambda == 0)
                    expr(log(!!x))
                else
                    expr(((!!x) ^ lambda - 1) / lambda)
            )
        }  
   } else
        function(lambda) {
            if (lambda == 0)
                log(x)
            else
                (x ^ lambda - 1) / lambda
        }
}
