  flag_lwd = 1,
  flag_line_color = NA,
  flag_radius_scale = 1,
  circle_color = NA,
  circle_lwd = 0.5,
  plot_names = FALSE,
  plot_name_size = 3,
  font_family = "sans",
  plot = TRUE
)

Arguments

string skalar (manatory), one of the available flag IDs
color_map

color vector (a string, optional), the color map (must match the species vector in length)
flag_lwd

numeric skalar (optional), line width of the optional frame of the flag annotation
flag_line_color

color skalar (a string, optional), line width of the optional frame of the flag annotation
flag_radius_scale

circle_color

color skalar (a string, optional), the color of the background circle outline
circle_lwd

numeric skalar (optional), the width of the background circle outlines
plot_names

logical skalar (optional), should the species label be added?
