Draw a square bracket with a label on a ggplot

bracket(
  xmin = NULL,
  xmax = NULL,

  ymax = NULL,
  vertical = NULL,
  horizontal = NULL,
  open = NULL,
  bracket_shape = NULL,
  thickness = 2,
  bracket_color = "black",
  label = NULL,
  label_hjust = NULL,
  label_vjust = NULL,
  label_font_size = 5,
  label_font_face = "bold",
  label_color = "black",
  label_parse = FALSE
)

Arguments

bracket(6.1, 6.2, 17, 22, bracket_shape = "]", label = "abc")
