  mode = units_options("set_units_mode"))
# S3 method for errors
set_units(x, value, ...,
  mode = units_options("set_units_mode"))
# S3 method for quantities
mixed_units(x, values, ...)
# S3 method for errors
mixed_units(x, values, ...)

Arguments

x

numeric vector, or object of class units

value

object of class units or symbolic_units, or in the case of set_units expression with symbols that can be resolved in ud_units (see examples).

...

passed on to as_units
