transfer.cross_projector: Compatibility wrapper for multivarious::transfer

In genpca: Generalized Principal Component Analysis

Compatibility wrapper for multivarious::transfer

Description

Provides a transfer method that accepts source/target arguments used in the tests. The method forwards to multivarious's transfer method which expects from/to.

Usage

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

Arguments

x	A cross_projector object.
new_data	New data to transfer.
from	Source space ("X" or "Y").
to	Target space ("X" or "Y").
opts	Options list passed to multivarious::transfer.
...	Additional arguments. Legacy parameters source and target are accepted here for backwards compatibility but are deprecated; use from and to instead.

Value

Matrix with transferred data.

Examples

# Generate sample data
set.seed(123)
n <- 50
X <- matrix(rnorm(n * 10), n, 10)
Y <- matrix(rnorm(n * 8), n, 8)

# Create a cross projector using rpls
fit <- rpls(X, Y, K = 2)

# Transfer new X data to Y space
new_X <- matrix(rnorm(10 * 10), 10, 10)
transferred <- transfer(fit, new_X, from = "X", to = "Y")
