# numeric-row

The *numeric-row* **parser** will load data from one or more rows from a source data table into numeric **variables** within **collections.

It inherits attributes and data loading behaviors from the abstract *row* **parser** type - and it also inherits attributes from the *numeric* **parser** type, e.g. *merge*.

The numeric **variables** produced will be named after the row headers.

## Attribute - operator

The *operator* attribute is optional.

```
{
  "parser_type": "numeric-row",
  "collection": "collection_name",
  "variable": {...},
  
  // This is a numeric operator which will transform values
  // parsed from each row before loading them into
  // variables
  //
  // See column parser - numeric-transform for options
  //
  "operator": "log"
}
```

## Attribute - constant

The *constant* attribute is optional. If used, the *operator* attribute becomes required.

```
{
  "parser_type": "numeric-row",
  "collection": "collection_name",
  "variable": {...},
  "operator": "*",
  
  // This is a constant to apply in conjunction with the operator
  // to values parsed from each row
  //
  // For example, this will multiple all values by 10
  //
  "constant": 10
}
```
