Whittaker's biomes - data.frame

Description

A data.frame containing boundaries of biomes as mean annual temperature and precipitation. Digitized from Figure 5.5 in Ricklefs, R. E. (2008). The economy of nature. W. H. Freeman and Company. (Chapter 5, Biological Communities, The biome concept).

Usage

Whittaker_biomes

Format

A data frame with 775 rows and 4 variables:

	Variable		Type		Description
[, 1]	temp_c	,	numeric	:	Mean annual temperature (degree Celsius)
[, 2]	precp_cm	,	numeric	:	Mean annual precipitation (cm)
[, 3]	biome_id	,	numeric	:	Biome's id
[, 4]	biome	,	character	:	Biome's name

Details

Values in temp_c and precp_cm represent the vertices of the borders between biome polygons as they were digitized. For more details see Whittaker_biomes_dataset

Examples

library(plotbiomes)
library(ggplot2)
ggplot() +
 geom_polygon(data = Whittaker_biomes,
              aes(x      = temp_c,
                  y      = precp_cm,
                  fill   = biome),
              colour = "gray98", # colour of polygon border
              size   = 0.5)      # thickness of polygon border

# Run example in console with: example(Whittaker_biomes)
