group

Groups values from a continuous space into a discrete space given a list of adjacent range limits. Applies only to integer or decimal type values. The returned value is:

the text representation of the range, for instance: * ‘-10’ for range (-∞‥10), * ‘10-20’ for range [10..20), * ‘20+’ for range [20..+∞).
the text representation of the value if the value is defined as an outlier.

Syntax

group(array_of_bounds[, array_of_outliers])

Parameter	Description
`array_of_bounds`	A list of values that will be the bounds of the ranges.
`array_of_outliers`	An optional list of outlier values that will be not be grouped and will be returned as is.

Examples

Usage example, possible returned values are: -18, 18-35, 35-40, …, 70+

$('CURRENT_AGE').group([18,35,40,45,50,55,60,65,70]);

Support of optional outliers:

$('CURRENT_AGE').group([18,35,40,45,50,55,60,65,70],[888,999]);

In combination with map:

$('CURRENT_AGE').group([30,40,50,60],[888,999]).map({
   '-30' :  1,
   '30-40': 2,
   '40-50': 3,
   '50-60': 4,
   '60+':   5,
   '888':   88,
   '999':   99
 });
