Compatibility wrapper for multivarious::transfer — transfer.cross

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

# \donttest{
# 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")
# }
