vis_location_biome: Plot a diagram of biomes with sites as dots

In guillembagaria/ggbiome: Obtain and Plot Whittaker's Biome Information

Description

vis_location_biome produces a ggplot object showing the biomes as colored areas according to mean annual temperature (MAT) and mean annual precipitation (MAP), using the function vis_biome, and adds the sites on it according to their values of MAT and MAP, obtained using the function gd_get_biome if not provided.

Usage

vis_location_biome(data, si_lat, si_long, si_mat, si_map, point_labels,
  col_fill = "white", merge_deserts = FALSE)

Arguments

data	Data frame including either geographical coordinates (latitude and longitude) or climatic data (MAT and MAP).
si_lat	Character, name of the column containing latitude values in decimal degrees or, alternatively, if data not provided, a numeric value of latitude.
si_long	Character, name of the column containing longitude values in decimal degrees or, alternatively, if data not provided, a numeric value of longitude.
si_mat	Character, name of the column containing mean annual temperature values in degrees Celsius or, alternatively, if data not provided, a numeric value of MAT.
si_map	Character, name of the column containing mean annual precipitation values in millimeters or alternatively, if data not provided, a numeric value of MAP.
point_labels	A character vector the same length of the number of sites to be plotted, indicating site labels. If missing, no labels are plotted.
col_fill	A character vector the same length of the number of sites to be plotted, indicating the fill color for site points, or alternatively a character vector of length one indicating a single fill color for all sites. The default is white.
merge_deserts	Logical indicating if desert biomes should be merged in a single biome. By default, deserts are not merged.

Value

A ggplot object showing the biomes and sites.

Examples

# Create a data frame with coordinates
sites <- data.frame(site = c("A", "B"), lat = c(69.49, 41.43),
                    long = c(27.23, 2.07))

# Create a ggplot diagram of the biomes with sites
vis_location_biome(sites, si_lat = "lat", si_long = "long",
                   point_labels = sites$site)

# Alternatively, for one site
vis_location_biome(si_mat = 15.8, si_map = 622, col_fill = 'red')
