projector: Construct a 'projector' instance

In bbuchsbaum/multivarious: Extensible Data Structures for Multivariate Analysis

Construct a projector instance

Description

A projector maps a matrix from an N-dimensional space to d-dimensional space, where d may be less than N. The projection matrix, v, is not necessarily orthogonal. This function constructs a projector instance which can be used for various dimensionality reduction techniques like PCA, LDA, etc.

Usage

projector(v, preproc = prep(pass()), ..., classes = NULL)

Arguments

v	A matrix of coefficients with dimensions nrow(v) by ncol(v) (columns = components)
preproc	A prepped pre-processing object (S3 class pre_processor). Default is the no-op pass() preprocessor.
...	Extra arguments to be stored in the projector object.
classes	Additional class information used for creating subtypes of projector. Default is NULL.

Value

An instance of type projector.
