Dear R gurus, I have XY data giving the locations of tree seedlings that were surveyed during a 210 meter belt transect. This belt transect was taken by stretching a line across the field, then measuring all seedlings within 1 meter on either side of the line. The end result was XY coordinates and height for ~1,300 seedlings. I would like to use that data to calculate density of seedlings per 10 meters per species and relative species abundance in order to compare between this transect and other 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.
