Transfer from X domain to Y domain (or vice versa) in a cross_projector

Description

Convert between data representations in a multiblock or cross-decomposition model by projecting the input new_data from the from domain/block onto a latent space and then reconstructing it in the to domain/block.

Usage

## S3 method for class 'cross_projector'
transfer(x, new_data, from, to, opts = list(), ...)

Arguments

x	A cross_projector object.
new_data	The data to transfer.
from	Source domain ("X" or "Y").
to	Target domain ("X" or "Y").
opts	A list of options (see transfer generic).
...	Ignored.

Details

When opts$ls_rr is TRUE, the forward projection from the from domain is computed using a ridge-regularized least squares approach. The penalty parameter is taken from opts$lambda. Component subsetting via opts$comps is applied after computing these ridge-based scores.

Value

Transferred data matrix.
