R: Arithmetic Operators for ff vectors

+.ff_vector {ffbase} | R Documentation

## Arithmetic Operators for ff vectors

### Description

These binary operators perform arithmetic on numeric ff vectors. Arith family:

- Arith: `"+", "-", "*", "/", "^", "%%", "%/%"`

The operators require either `x` or `y` to be an `ff_vector` or both. In case either `x` or `y` is not an `ff_vector`, the other object needs to be of length 1. Recycling is not implemented.

### Usage

    ## S3 method for class 'ff_vector'
     x + y

    ## S3 method for class 'ff_vector'
     x - y

    ## S3 method for class 'ff_vector'
     x * y

    ## S3 method for class 'ff_vector'
     x / y

    ## S3 method for class 'ff_vector'
     x ^ y

    ## S3 method for class 'ff_vector'
     x %% y

    ## S3 method for class 'ff_vector'
     x %/% y

### Arguments

`x` | either a numeric `ff_vector` or a vector of length 1 in RAM in which case y should be an `ff_vector`
`y` | either a numeric `ff_vector` or a vector of length 1 in RAM in which case x should be an `ff_vector`

### Value

an `ff_vector`. For the definition of the operators see the base package of R.
