imSeven {numGen}

Item Model 7

Description

This uses item model 7 to create number series items - Identification of complex coefficients of change

Usage

imSeven(vOne = 1, vTwo = 3, items, seed = 1, logic = "one",
  random = FALSE)

Arguments

vOne

The first value in the complex coefficient (x). Can be a sequence of values or a specific value.

vTwo

The second value in the complex coefficient (y). Can be a sequence of values or a specific value.

items

Generate a random mix of items.

seed

To get the same random sampling of items

logic

"one" or "two"

random

If random=FALSE, the items will follow in sequential order.

Details

This function creates number series that is a combination of Arithmetic, Linear and Complex coefficient. Ability to identify complex coefficients; the coefficient of change involves a combination of arithmetic operations (e.g. addition and multiplication) applied serially.
There are two logic to calculate the number series. First logic of complex coefficient = i*x+y.
Second logic of complex coefficient = (i+x)*y.
. Example: Each element in the sequence is derived from the preceding by adding two and multiplying the result by two. (2 8 20 44 92 (188)).

Examples

#Draws 5 items randomly.
imSeven(vOne=1,vTwo=3,items=5,seed=2,logic="one",random=TRUE)

# Calculates all combinations
# Items and seed arg is ignored.
imSeven(vOne=1:2,vTwo=1:3,items=5,seed=2,logic="one",random=FALSE)
