getPP3projdata {PP3}R Documentation

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

Details

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

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.
