Temporal RDM wrapper for formula usage — temporal • rMVPA

Convenience wrapper for temporal_rdm that simplifies usage in RSA formulas.

Usage

temporal(index, block = NULL, ..., as_dist = TRUE)

Arguments

index: numeric or integer vector representing trial order or time
block: optional vector of run/block identifiers
...: additional parameters passed to temporal_rdm
as_dist: logical; if TRUE return a dist object (default TRUE)

Value

A dist object or matrix representing temporal relationships

Details

This function provides a shorter name for use in RSA design formulas. It calls temporal_rdm with the same parameters.

Examples

run_ids <- rep(1:4, each = 10)
set.seed(1)
task_rdm <- dist(matrix(rnorm(40 * 3), 40, 3))

# Build a temporal nuisance RDM and use it in an RSA design
rdes <- rsa_design(
  ~ task_rdm + temp_rdm,
  data = list(task_rdm = task_rdm,
              temp_rdm = temporal(1:40, block = run_ids, kernel = "adjacent", width = 2),
              run = run_ids),
  block_var = ~ run
