Reprocess data for Nyström approximation

Description

Apply preprocessing to new data for projection using a Nyström approximation. This method overrides the default reprocess.projector to handle the fact that Nyström components are in kernel space (not feature space).

Usage

## S3 method for class 'nystrom_approx'
reprocess(x, new_data, colind = NULL, ...)

Arguments

x	A nystrom_approx object
new_data	A matrix with the same number of columns as the original training data
colind	Optional column indices (not typically used for Nyström)
...	Additional arguments (ignored)

Value

Preprocessed data matrix
