pool.plot: Plot species from the pool

Description

Plot all species from the study case and associated convex hull

Usage

pool.plot(
  ggplot_bg,
  sp_coord2D,
  vertices_nD,
  plot_pool = TRUE,
  shape_pool = 3,
  size_pool = 0.8,
  color_pool = "grey95",
  fill_pool = NA,
  color_ch = NA,
  fill_ch = "white",
  alpha_ch = 1,
  shape_vert = 3,
  size_vert = 1,
  color_vert = "black",
  fill_vert = NA
)

Value

A ggplot object plotting background of multidimensional graphs and species from the global pool (associated convex hull if asked).

Arguments

ggplot_bg

a ggplot object of the plot background retrieved through the background.plot function.

sp_coord2D

a list of matrix (ncol = 2) with coordinates of species present in the pool for a given pair of axes

vertices_nD

a list (with names as in sp_coord2D) of vectors with names of species being vertices in n dimensions.

plot_pool

a logical value indicating whether species of each assemblage should be plotted or not. Default: plot_pool = TRUE.

shape_pool

a numeric value referring to the shape used to plot species pool. Default: shape_pool = 16(filled circle).

size_pool

a numeric value referring to the size of species belonging to the global pool. Default: size_pool = 1.

color_pool

a R color name or an hexadecimal code referring to the color of the pool. This color is also used for FRic convex hull color. Default: color_pool = "#0072B2".

fill_pool

a R color name or an hexadecimal code referring to the colour to fill species symbol (if shape_sp > 20) and the assemblage convex hull. Default: fill_pool = '#0072B2'.

color_ch

a R color name or an hexadecimal code referring to the border of the convex hull filled by the pool of species. Default: color_ch = "black".

fill_ch

a R color name or an hexadecimal code referring to the filling of the convex hull filled by the pool of species. Default is: fill_ch = "white".

alpha_ch

a numeric value for transparency of the filling of the convex hull (0 = high transparency, 1 = no transparency). Default: alpha_ch = 0.3.

shape_vert

a numeric value referring to the shape used to plot vertices if vertices should be plotted in a different way than other species. If shape_vert = NA, no vertices plotted. Default: shape_vert = NA.

size_vert

a numeric value referring to the size of symbol for vertices. Default: size_vert = 1.

color_vert

a R color name or an hexadecimal code referring to the color of vertices if plotted. If color_vert = NA, vertices are not plotted (for shapes only defined by color, ie shape inferior to 20. Otherwise fill must also be set to NA). Default: color_vert = NA.

fill_vert

a character value referring to the color for filling symbol for vertices (if shape_vert >20). If fill = NA and color = NA, vertices are not plotted (if shape_vert superior to 20. Otherwise color_vert = NULL is enough). Default is NA.
