PP3 (version 1.2)

getPP3projdata: Extract projected data from a PP3 object.

Description

Extract projected data solution from a PP3 object.

Usage

getPP3projdata(PP3, number)

Arguments

PP3

The PP3 object you wish to get information from

number

The solution number you want to know about

Value

The three-dimensional projected data associated with projection solution number. This is a matrix of three rows (one for each projected direction) versus N columns, where N is the number original cases.

Details

The projected data associated with a projection solution (out of the nrandstarts that were executed by PP3many)) can be extracted using this function.
