AddDoubleRule-class: Class '"AddDoubleRule"'

In ruleR: Generating numeric sequence items for intelligence tests

Description

A class for the rule which adds the two previous elements of a number sequence. It inherits from class DoubleRule

Objects from the Class

Objects can be created by calls of the form new("AddDoubleRule",... ).

Slots

firstRule:

Object of class "SingleRule" - a rule to be executed on the first element of numeric sequence, before executing DoubleRule (doesn't need to be specified)

secondRule:

Object of class "SingleRule" - a rule to be executed on the second element of numeric sequence, before executing DoubleRule (doesn't need to be specified)

nextSingle:

Object of class "SingleRule" - a rule to be executed on the result of DoubleRule (doesn't need to be specified)

.S3Class:

Object of class "character" - S3 methods apply for these objects

Extends

Class "DoubleRule", directly.

Methods

Examples

#[1] simple DoubleRule

p <- new("AddDoubleRule")
calculate(p,12,5) #12+5=17
unlist(sequenceR(1,p,8)[[1]]) # first 8 elements of Fibonacci sequence


#[2] combining rules

m <- new("DigSumSingleRule") 
# SingleRule that calculates digitsum of an element of numeric sequence

r <- new("AddConstSingleRule", constantVal=6)
# a SingleRule that adds constant value '6' to the element of numeric sequence 

f <- new("MultConstSingleRule", constantVal=2)
# a SingleRule that muliplies an element of a sequence by constant value '4'

g <- new("AddDoubleRule", firstRule=r, secondRule=f, nextSingle=m)
calculate(g,12,5) #10

## How is rule 'g' executed ?
## Starting elements are '12' and '5'
## Rule 'r'(firstRule) is applied to the first element of numeric sequence (12+6=18)
## Rule 'f'(secondRule) is applied to the second element of numeric sequence (5*2=10)
## "AddDoubleRule" is executed on the results of firstRule and secondRule (18+10=28)
## Rule 'm' is applies to the result of DoubleRule (2+8=10)
