kmiita2SR: Convert an IITA result into a surmise relation matrix

In kstMatrix: Basic Functions in Knowledge Space Theory Using Matrix Representation

Convert an IITA result into a surmise relation matrix

Description

kmiita2SR takes the result of a DAKS::iita() call and delivers the matrix of the computed surmise relation.

Usage

kmiita2SR(ii, names = NULL, items = 0)

Arguments

ii	iita() result
names	Vector of item names (default NULL)
items	Minimal number of items (default 0)

Value

Surmise relation matrix

The iita() function looses information on the item names and uses consecutive numbers instead. The implications part of its result does not give any hint on isolated items, i.e. items which# neither have a prerequisite nor are prerequisite of any other item. Therefore, a minimal number of items can be passed to kmiita2SR(). If the highest item number within implications is higher, this items parameter is ignored.
