Representation of sites selected to be surveyed

Description

Plots representing sites (all and selected for survey) in environmental and/or geographic space.

Usage

plot_sites_EG(master_selection, selection_type, variable_1 = NULL,
              variable_2 = NULL, selection_number = 1,
              region_border = TRUE, mask_border = FALSE, col_all = NULL,
              col_sites = NULL, col_pre = NULL, cex_all = 0.7,
              cex_sites = 1, cex_pre = 1, pch_all = 16, pch_sites = 16,
              pch_pre = 16, add_main = TRUE)

Arguments

master_selection

master_selection object derived from functions random_selection, uniformG_selection, uniformE_selection, or EG_selection.

selection_type

(character) type of selection depending on the function used to select sites. The options available are "random" (random_selection), "G" (uniformG_selection), "E" (uniformE_selection), and "EG" (EG_selection).

variable_1

(character or numeric) name or position of the first variable (x-axis) to be plotted in environmental space. Default = NULL, required when selection_type = "random" or "G".

variable_2

(character or numeric) name or position of the second variable (y-axis) to be plotted in environmental space. It must be different from the first one. Default = NULL, required when selection_type = "random" or "G".

selection_number

(numeric) number of selection to be plotted. Default = 1.

region_border

(logical) whether to add region border to the plot. Default = TRUE.

mask_border

(logical) whether to add mask border to the plot. Ignored if mask is not present in master_selection. Default = FALSE.

col_all

colors for points in all points in the region of interest. The default, NULL, uses a light gray color.

col_sites

color for selected sites. The default, NULL, uses a blue color to represent selected sites.

col_pre

color for preselected sites. The default, NULL, uses a red color to represent preselected sites. Ignored if preselected sites are not present in master_selection.

cex_all

(numeric) value defining magnification of all points relative to the default. Default = 0.7.

cex_sites

(numeric) value defining magnification of selected sites relative to the default. Default = 1.

cex_pre

(numeric) value defining magnification of preselected sites relative to the default. Default = 1. Ignored if preselected sites are not present in master_selection.

pch_all

(numeric) integer specifying a symbol when plotting all points. Default = 16.

pch_sites

(numeric) integer specifying a symbol when plotting points of selected sites. Default = 16.

pch_pre

(numeric) integer specifying a symbol when plotting points of preselected sites. Default = 16. Ignored if preselected sites are not present in master_selection.

add_main

(logical) whether or not to add fixed titles to the plot. Default = TRUE. Titles added are "Environmental space" and "Geographic space".

main

(character) the main title for the plot.

xlab

(character) label for the x axis. The default, NULL, uses variable_1.

ylab

(character) label for the y axis. The default, NULL, uses variable_2.

Value

plot_sites_EG returns a two-panel plot showing the selected sites. They are show in both spaces, geographic and environmental.

plot_sites_E returns a plot of selected sites in environmental space.

plot_sites_G returns a plot of selected sites in geographic space.

Examples

# Data
data("m_selection", package = "biosurvey")

# Plotting
plot_sites_EG(m_selection, selection_type = "E")
plot_sites_E(m_selection, selection_type = "E")
plot_sites_G(m_selection, selection_type = "E")
