Creates a graph using the climate and elevation data which has
been extracted for a given location. It accepts the data formatted
from the ce_extract function.
plot_h(data, geo_id, col = "red", pch = 19, ...)Arguments
- data
List. Containing climate, elevation and latitude data sets. Structured by
ce_extract().- geo_id
Character. Corresponding to a specific feature contained in the
"location"argument (specifically in the"location_g"column).- col, pch, ...
Arguments to control point styling in
HoldridgePoints().
Value
Returns a base R family of plot. This function uses the Ternary
package to create a Holdridge simplex plot.

# Step 1. Import the Italian Biome polygon data
# Step 2. Run the download function
# Step 3. Run the extract function
#* See ce_download & ce_extract documentation
# Steps 1, 2 & 3 can be skipped by loading the extracted data (it_data)
