plotDispersionField: Plot dispersion fields

In epm: EcoPhyloMapper

Plot dispersion fields

Description

For a set of specified coordinates, plot a richness map for the species that are found at those coordinates.

Usage

plotDispersionField(
  x,
  coords,
  plotCoords = TRUE,
  legend = TRUE,
  col,
  lwd = 0.5,
  basemap = "worldmap",
  borderCol = "black",
  alpha = 1,
  includeFrame = FALSE,
  use_tmap = FALSE,
  add = FALSE
)

Arguments

x	object of class epmGrid
coords	coordinates as either a spatial points object (sp or sf), a matrix/dataframe with two columns or a numeric vector of c(long, lat).
plotCoords	boolean; should the coordinates be plotted as well?
legend	boolean; should legend be included?
col	either a vector of color names that will be interpolated, or a color ramp function that takes an integer (see for example colorRampPalette).
lwd	grid cell border width
basemap	if 'none', then only the grid is plotted. If 'worldmap', then vector map is plotted. If 'interactive', then the mapview package is used.
borderCol	color for grid cell borders
alpha	opacity of all colors and borders, ranging from 0 (fully transparent) to 1 (fully opaque)
includeFrame	boolean; include frame around plot?
use_tmap	boolean; if FALSE, plotting will be done via sf instead of tmap package
add	logical, add to existing plot?

Details

Assemblage dispersion fields represent an overlapping of geographic ranges for the taxa that occur in the focal grid cells.

Value

Nothing is returned.
