numeric-slice

The numeric-slice parser will evaluate or load data from a single column in comparison with a numeric constant value. Depending on the value of the operator attribute, the column's data will evaluate to true, false, or null.

It inherits attributes and behaviors from its parent: abstract parser - boolean.

Note - in the case where a numeric-slice parser is used to create a categorical variable - it is usually a better option to use a numeric-map parser instead - especially to avoid needing multiple numeric-slice parsers to map all data cases from a column into different variables.

Attribute - operator

The operator attribute is required.

{
  "parser_type": "numeric-slice", 
  "column": "cccc",
  "value": ####,
  
  // The operator attribute defines a comparison function.
  // Options include: 
  // "=" - equals
  // "!=" - not equals
  // "<" - column value is less than the constant value
  // "<=" - column value is less than or equal to the constant value
  // ">" - column value is greater than the constant value
  // ">=" - column value is greater than or equal to the constant value
  //
  "operator": ">"
}

Attribute - value

The value attribute is required.

{
  "parser_type": "numeric-slice", 
  "column": "cccc",
  "operator": ">",
  
  // The value attribute defines a constant value against which
  // the parser will evaluate dynamic values from the column.
  //
  "value": ####
