ff_ops: Ops for ff vectors

In ffbase: Basic Statistical Functions for Package 'ff'

Description

These operators implement ff_vector specific operators and handle the following operators from the Ops family:

• Compare: "==", "!=", "<", "<=", ">=", ">"

• Logic: "&", "|", "!"

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

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

## S3 method for class 'ff_vector'
 !x

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.
