getPP3index: Extract projection index values from a PP3 object.

In PP3: Three-Dimensional Exploratory Projection Pursuit

Description

Extract project index value vector from a PP3 object.

Usage

getPP3index(x, number)

Arguments

x	PP3 object to get indices from.
number	Identification number of solution. Optional

Details

If number is missing then the whole projection index vector is returned. If number is specified then the projection index associated with that identification number is returned.

Value

Either a vector of indices, or a single index, depending on whether number is not specified or it is, respectively.
