summary.range Function (GPL)

Syntax

summary.range(<algebra>)

or 

summary.range(<binning function>)

or 

summary.range(<statistic function>)

<algebra>. Graph algebra, such as x*y. Refer to Brief Overview of GPL Algebra for an introduction to graph algebra.

<binning function>. A binning function.

<statistic function>. Another statistic function. The result of the embedded statistic is used to calculate summary.range.

Description

Calculates the range, which is the difference between the minimum and maximum values. If the function is evaluating graph algebra, the range of the analysis variable is returned. For more information about analysis variables, see the discussion in Brief Overview of GPL Algebra .

This function returns only one value. If you want to display the interval between the minimum and maximum values, use region.spread.range. See the topic region.spread.range Function (GPL) for more information.

Examples

Figure 1. Example: Calculating the range of salary for each jobcat category
ELEMENT: interval(position(summary.range(jobcat*salary)))
