Extract Per-ROI Predicted and Observed RDM Vectors from Feature RSA Results

Convenience helper to pull the compact lower-triangle predicted (and optionally observed) RDM vectors stored by feature_rsa_model(..., return_rdm_vectors = TRUE) from a regional_mvpa_result.

Usage

feature_rsa_rdm_vectors(x)

Arguments

x

A regional_mvpa_result returned by run_regional() for a feature_rsa_model, or a tibble/data frame with columns roinum and rdm_vec.

Value

A tibble with one row per ROI and columns:

roinum

ROI id.

n_obs

Number of observations contributing to the vector.

observation_index

List-column of observation ordering used for the predicted RDM.

rdm_vec

List-column containing the lower-triangle predicted RDM vector for that ROI.

observed_rdm_vec

List-column containing the lower-triangle observed RDM vector for that ROI (if available).

Examples

if (FALSE) { # \dontrun{
res <- run_regional(
  feature_rsa_model(dataset, design, method = "pls", return_rdm_vectors = TRUE),
  region_mask
)
vecs <- feature_rsa_rdm_vectors(res)
} # }
