  ylab = NULL,
  custom_theme = cowplot::theme_minimal_hgrid()
)

Examples

data <- dplyr::tibble(
  Group1 = rep(LETTERS[1:5], each = 10),
  Group2 = rep(LETTERS[6:15], each = 5),
  zzzz = c(rep("xx", 20), rep("yy", 20), rep(NA, 10))
)
p1 <- show_group_mapping(data, col_to_flow = "Group1", cols_to_map = colnames(data)[-1])
p1

p2 <- show_group_mapping(data,
  col_to_flow = "Group1", cols_to_map = colnames(data)[-1],
  include_sig = TRUE
)
