Plot Number of Sites by Species

Represent all species in each function of the number of sites they occupy. The species are ordered from the ones that occupy the least number of sites from the ones that occupy the most. The number of site is indicated at the bottom x-axis, while the top x-axis represents the proportion of occupied sites. The left y-axis label species names and their rank by increasing prevalence. The user can supplied a threshold of sites to see how many species occupy more or less than the given proportion of sites.

Usage

fb_plot_number_sites_by_species(
  site_species,
  threshold_sites_proportion = NULL
)

Arguments

site_species

a data.frame with sites in rows and species in columns. NOTE: the first column should be named "site" and indicate site names. The other columns should be named according to species names.

threshold_sites_proportion

a numeric of length 1 between 0 and 1. The percentage of sites coverage threshold.

Value

a ggplot2 object

Examples

fb_plot_number_sites_by_species(site_species)
#> There are more than 30 species, the y-axis will label the position of 30 evenly spaced species (along their prevalence)


# Add a vertical cutoff line (40% of sites)
fb_plot_number_sites_by_species(site_species, 0.4)
#> There are more than 30 species, the y-axis will label the position of 30 evenly spaced species (along their prevalence)
