Project a specific block (subject) using a hatsa_projector object — project_block.hatsa

Retrieves the aligned spectral sketch for a specified subject. If new data for that subject is provided, it projects that new data. Otherwise, it extracts the stored aligned sketch from the original analysis.

Usage

# S3 method for class 'hatsa_projector'
project_block(object, newdata = NULL, block, ...)

Arguments

object: A fitted hatsa_projector object.
newdata: Optional. A single numeric matrix of parcel time-series data (T_i x V_p) for the subject specified by block. If NULL, the stored sketch for the block is returned. If provided, this new data is projected.
block: An integer, the index of the subject (block) to project.
...: Additional arguments passed to predict.hatsa_projector if newdata is provided.

Value

A matrix (V_p x k) representing the aligned spectral sketch for the specified subject/block. Returns NULL or raises an error if the block is invalid or data is inappropriate.
