plot_ranges: Helper to plot multiple ranges on top of environmental layers

In rangemap: Simple Tools for Defining Species Ranges

Description

Helper to plot multiple ranges on top of environmental layers

Usage

plot_ranges(sp_ranges, sp_records = NULL, variable, range_colors = NULL,
            color_variable = NULL, xlim = NULL, ylim = NULL)

Arguments

sp_ranges	list of SpatialPolygonsDataFrame objects representing species ranges.
sp_records	a SpatialPointsDataFrame of species occurrences.
variable	a RasterLayer representing an environmental variable.
range_colors	vector of colors for borders of species ranges. If NULL, the default, distinct levels of gray will be used.
color_variable	a color palette (a vector of continuous colors generated by functions like heat.colors). If NULL, the default, rev(terrain.colors(255)) will be used.
xlim	the x limits (x1, x2) of the plot. NULL indicates that the range of values to be plotted will define limits.
ylim	the y limits (x1, x2) of the plot.

Value

A plot showing species ranges on top of a environmental variable.

Examples

# example data
data("buffer_range", package = "rangemap")
data("cxhull_range", package = "rangemap")

ranges <- list(buffer_range@species_range, cxhull_range@species_range)

var <- raster::stack(system.file("extdata", "variables.tif",
                                 package = "rangemap"))[[1]]

# plotting
plot_ranges(ranges, variable = var)
