Using XY location data to calculate ecological parameters
...her transects as well as to compare between segments of the same transect. Are there any R packages out there that will allow me make those calculations? To give an idea of my data, here's a fictional example: Species X (m) Y(m) Acer negundo 90.10 -.19 Acer negundo 90.14 -.90 Acer saccharinum 90.25 .54 Acer rubrum 90.89 .21 Acer negundo 91.25 .36 Acer negundo 91.46 -.65 etc. Thanks.
