With this R project, soil data from oceanographical campaigns can be input into a script to generate a ternary plot, placing points of each station according to its amount of sand, clay, and silt. Data can be organized in an Excel file, using a column for the stations and three columns for each of sand, clay or silt like in this example:
| station | sand | clay | silt |
|---|---|---|---|
| a1 | 33 | 43 | 24 |
| a2 | 12 | 62 | 26 |
| a3 | 29 | 54 | 17 |
The script is set up to read csv files, but can be manipulated to read Excel files. If you'd rather not change the script, then export your Excel file as a csv file.
Sample data to test the script can be found in the raw folder.
