Assert that a value may either be a column name in the data (first) or a single unit value (second)

Description

Assert that a value may either be a column name in the data (first) or a single unit value (second)

Usage

assert_unit_col(unit, data)

assert_unit_value(unit)

assert_unit(unit, data)

Arguments

unit	The column name or unit value
data	The data.frame that contains a column named unit

Value

unit with an attribute of "unit_type" that is either "column" or "value", or NULL if is.null(unit)

Functions

• assert_unit_col(): Assert that a column name contains a character string (that could be a unit specification)

• assert_unit_value(): Assert that a value may be a single unit

  The function does not verify that it is a real unit like "ng/mL" only that it is a single character string.
