Compute Rotation Recovery (SO(k) Alignment) Metrics — compute_rotation

Assesses how accurately the subject-specific rotation matrices (`R_i`) estimated by HATSA match the true rotations.

Usage

compute_rotation_recovery(hatsa_object, R_true_list, ...)

Arguments

hatsa_object: A fitted `hatsa_projector` object, which contains `R_final_list` (list of estimated k x k rotation matrices).
R_true_list: A list of true k x k rotation matrices, corresponding to each subject in `hatsa_object`.
...: Additional arguments passed to `misalign_deg` function.

Value

A numeric vector of misalignment angles in degrees, one for each subject. Returns `NA` for subjects where either the estimated or true rotation is missing or invalid for comparison.
