Examples

  # save current graphical parameter setting
  old.par <- graphics::par(no.readonly = TRUE)

  for (i in 2:5) {

    graphics::par(mfrow = kwb.plot::bestRowColumnSetting(i))

    for (j in 1:i) {
      plot(seq_len(j), main = paste0("j = ", j, "/", i))
    }
  }

  # restore graphical parameter setting
  graphics::par(old.par)
