Whittaker_biomes | R Documentation |
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).
Whittaker_biomes
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 |
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
