Create an attribute in Interval or Ratio Measurement Scales

Description

Create an attribute in Interval or Ratio Measurement Scales

Usage

create_interval_ratio(
  type = c("interval", "ratio"),
  units,
  number_type,
  unit_precision = NULL,
  minimum = NULL,
  maximum = NULL
)

Arguments

type	Either "interval" or "ratio". Use "interval" to define data which consist of equidistant points on a scale. Use "ratio" to define data which consists not only of equidistant points but also has a meaningful zero point, which allows the ratio to have meaning.
units	The units assigned to this attribute.
number_type	What type of number. Examples given in exported documentation.
unit_precision	How precise this attirbutes' measurements are recorded.
minimum	Optional. Theoretical or allowable minimum value. Values can be larger than or equal to this number.
maximum	Optional. Theoretical or allowable maximum value. Values can be less than or equal to this number.

                          attribute_definition = "Number of individuals observed",
