Compute the inverse projection of a columnwise subset of the component matrix (e.g., a sub-block). Even when the full component matrix is orthogonal, there is no guarantee that the partial component matrix is orthogonal.
partial_inverse_projection(x, colind, ...)A matrix representing the partial inverse projection.
A fitted model object, such as a projector, that has been fit to a dataset.
A numeric vector specifying the column indices of the component matrix to consider for the partial inverse projection.
Additional arguments to be passed to the specific model implementation of partial_inverse_projection.
