plot_DI: Plotting dissimilarity indices withing and among sets of selected sites

Description

Creates matrix-like plots of dissimilarities found among communities of species in distinct sites selected or sets of sites selected for sampling.

Usage

plot_DI(DI_selected_sites, selection_type = "selections",
        selection_number = 1, values = TRUE,
        col = heat.colors(12, rev = TRUE),
        xlab = "", ylab = "")

Arguments

DI_selected_sites

list of results obtained with function selected_sites_DI.

selection_type

type of selection to be considered when creating DI matrix plot. Options are: "selections", "random", "E", "G", and "EG". The default, "selections", plots a comparison among all selection types.

selection_number

(numeric) number of selection to be plotted. Default = 1. Ignored if selection_type = "selections".

values

(logical) whether or not to add values of dissimilarity. Default = TRUE.

col

a list of colors derived from a palette. Default = heat.colors(12, rev = TRUE).

xlab

(character) label for x axis of plot. Default = "Number of sites".

ylab

(character) label for y axis of plot. Default = "Species".

Value

A plot of a matrix of dissimilarities among sites selected for sampling, or among sets of sampling sites selected. Random is abbreviated as "R" in labels.

Examples

# NOT RUN {
# Data
data("b_pam", package = "biosurvey")
data("m_selection", package = "biosurvey")

# Subsetting base PAM according to selections
sub_pam_all <- subset_PAM(b_pam, m_selection, selection_type = "all")

# Calculating dissimilarities
DI_sel <- selected_sites_DI(sub_pam_all)

# Plotting
plot_DI(DI_sel)
# }
