Examples

if (requireNamespace("fastICA", quietly = TRUE) &&
    requireNamespace("GGally", quietly = TRUE)) {
  datamat <- matrix(rnorm(240), nrow = 8)
  dataset <- list(
    data = datamat,
    metadata = data.frame(
      class = factor(rep(c("A", "B"), each = 15))
    )
  )

  ica.result <- ica_analysis_dataset(
