Apply a transform to data

Apply a transform to data

Usage

apply_transform(transform, X, ...)

Arguments

transform

An alignment transform object (typically from relative_transform or new_align_transform)

X

A data matrix to transform (samples x features)

...

Additional arguments passed to methods

Value

A transformed data matrix. For orthogonal/linear groups, returns X For permutation group, returns op

Examples

# Create a simple orthogonal transform
R <- diag(3)
tr <- new_align_transform("O", R, from = 1, to = 2)
X <- matrix(rnorm(12), 4, 3)
X_transformed <- apply_transform(tr, X)
